CRAFTSMAN CMXGWFN061294 3100 PSI 2.4 GPM Cold-Water Gas Pressure Washer with 163cc Engine and 4 Spray Tips

Product Description

The CRAFTSMAN CMXGWFN061294 Gas Pressure Washer delivers up to 3,100 PSI of pressure and 2.4 GPM of water flow, providing the cleaning performance needed for demanding residential outdoor-maintenance projects.

Powered by a 163cc CRAFTSMAN gasoline engine, this pressure washer is suitable for cleaning driveways, sidewalks, patios, decks, fencing, home siding, outdoor furniture, vehicles, lawn equipment, and other durable outdoor surfaces.

Its maintenance-free OEM Technologies axial-cam pump features a sealed crankcase, corrosion-resistant construction, and thermal-relief protection. Because the pump crankcase is sealed and factory lubricated, routine pump-oil changes are not required. Engine oil is still required and must be checked and changed according to the operating manual.

The pressure washer includes four quick-connect spray nozzles, an onboard detergent tank, a professional-style spray gun, an extension lance, and a flexible high-pressure hose. Large 12-inch never-flat wheels help the machine travel across driveways, grass, patios, and other surfaces without requiring tire-pressure maintenance.

The CRAFTSMAN 3100 PSI pressure washer is intended for homeowners who need more cleaning force and rinsing capability than a typical electric pressure washer while maintaining a compact and portable residential design.

3100 PSI Cleaning Pressure

The pressure washer produces up to 3,100 PSI, providing concentrated cleaning force for removing dirt, mud, mildew, algae, road film, and other outdoor buildup.

This level of pressure is suitable for cleaning durable surfaces such as:

• Concrete driveways
• Sidewalks
• Patios
• Brick surfaces
• Fencing
• Decks
• Outdoor steps
• Lawn equipment
• Garbage containers
• Vehicle tires and wheel wells

The full 3,100 PSI output should not be used on every surface. Painted materials, soft wood, vehicle finishes, windows, screens, siding, seals, and outdoor furniture can be damaged by excessive pressure or an incorrectly selected nozzle.

Always begin with a wider spray pattern and test a small, hidden area before cleaning the entire surface.

2.4 GPM Water Flow

The washer delivers up to 2.4 gallons per minute of water flow.

Pressure helps break dirt away from a surface, while flow rate carries the loosened material away. The combination of 3,100 PSI and 2.4 GPM provides approximately 7,440 cleaning units, creating a strong balance between concentrated pressure and rinsing volume.

The connected water source must provide a steady and unrestricted supply. Insufficient inlet flow can cause pressure fluctuation, pump cavitation, overheating, and premature pump wear.

Before starting the engine:

• Connect the garden hose securely.
• Turn the water supply fully on.
• Inspect the hose for kinks or restrictions.
• Squeeze the spray-gun trigger to remove trapped air.
• Confirm that water flows steadily through the spray wand.

The pump must never be operated without an active water supply.

163cc CRAFTSMAN Gasoline Engine

The pressure washer is powered by a 163cc CRAFTSMAN four-stroke gasoline engine with a large recoil starter.

The engine provides the torque required to operate the pump at its rated pressure and flow. It also features automatic low-oil shutdown, which helps protect the engine if the oil level falls below a safe operating range.

The engine uses separate gasoline and engine oil. Oil must not be mixed into the fuel.

Routine engine maintenance includes:

• Checking engine oil before each use
• Changing engine oil at the recommended intervals
• Inspecting and cleaning the air filter
• Replacing the air filter when necessary
• Inspecting the spark plug
• Cleaning engine cooling areas
• Using fresh unleaded gasoline
• Preparing the fuel system for long-term storage

The recommended engine-oil grade is 10W-30, and the listed oil capacity is approximately 20.48 fluid ounces.

Manual Recoil Starting

The CMXGWFN061294 uses a manual pull-start system.

A large recoil starter helps provide a secure grip when starting the engine. For easier startup, the water supply should be connected and turned on, and pressure should be released from the spray gun before pulling the starter cord.

This model does not include:

• Electric start
• Battery starting
• Remote start

Starting instructions should always be followed in the order provided in the owner’s manual.

Maintenance-Free Axial-Cam Pump

The pressure washer uses an OEM Technologies axial-cam pump.

The pump features:

• Maintenance-free sealed crankcase
• Factory-installed lubrication
• Anodized die-cast aluminum construction
• Corrosion resistance
• Thermal-relief protection
• Direct-drive configuration

The sealed pump does not require routine pump-oil changes. This applies only to the pump; the gasoline engine still requires engine oil and scheduled oil changes.

Axial-cam pumps are compact and well suited to residential pressure washers. They provide strong cleaning performance without the additional service requirements associated with some commercial triplex pumps.

Thermal-Relief Protection

When the spray-gun trigger is released, water circulates through the pump’s bypass system.

If the washer remains in bypass too long, the recirculating water can become hot. The thermal-relief valve helps protect the pump by releasing overheated water and allowing cooler inlet water to enter.

Thermal-relief protection is a safety feature, but the machine should not be left running for extended periods with the trigger released.

For longer pauses, switch off the engine.

Cold-Water Cleaning System

This is a cold-water pressure washer. It does not contain a burner or internal water-heating system.

The machine should be connected to a clean cold-water supply unless the operating manual specifically allows a different inlet temperature.

Hot water should not be supplied from a household water heater without verifying the maximum inlet-temperature rating. Excessively hot inlet water can damage pump seals and internal components.

For oily or greasy contamination, a compatible pressure-washer detergent may improve performance.

Integrated Detergent Tank

An onboard detergent tank allows compatible cleaning solution to be carried directly on the pressure washer.

The detergent system operates with the low-pressure soap nozzle. When the soap nozzle is installed, the pump creates the low-pressure condition needed to draw detergent into the water stream.

The onboard tank is useful for cleaning:

• Siding
• Fencing
• Decking
• Outdoor furniture
• Vehicles
• Garbage containers
• General outdoor surfaces

Only detergents labeled for pressure-washer use should be added.

Do not use:

• Flammable solvents
• Paint thinner
• Gasoline
• Undiluted corrosive chemicals
• Unapproved bleach mixtures
• Chemicals that may damage aluminum or pump seals

After detergent use, flush the system with clean water to prevent buildup inside the siphon system and spray accessories.

Four Quick-Connect Spray Nozzles

The pressure washer includes four professional-style quick-connect spray tips:

• 0-degree nozzle
• 15-degree nozzle
• 40-degree nozzle
• Low-pressure soap nozzle

The quick-connect system allows the spray pattern to be changed without replacing the entire lance.

0-Degree Nozzle

The 0-degree nozzle creates a highly concentrated pencil jet.

It provides the strongest cleaning action but covers a very small area. It should only be used on extremely durable materials and stubborn contamination.

It can quickly damage:

• Wood
• Paint
• Siding
• Vehicle finishes
• Glass
• Rubber seals
• Outdoor furniture

15-Degree Nozzle

The 15-degree nozzle creates a narrow fan spray for strong cleaning on durable surfaces.

It is useful for:

• Concrete
• Brick
• Driveways
• Sidewalks
• Metal equipment
• Stubborn surface buildup

40-Degree Nozzle

The 40-degree nozzle produces a wider and gentler spray pattern.

It is suitable for:

• Vehicles
• Outdoor furniture
• Painted surfaces
• Siding
• General rinsing
• More delicate cleaning applications

Working distance should still be adjusted to protect the cleaned material.

Soap Nozzle

The soap nozzle creates the low-pressure spray needed for detergent application.

It is normally used at the beginning of the cleaning process. After the detergent has had time to loosen contamination, a suitable high-pressure nozzle can be installed for rinsing.

Do not allow detergent to dry on the surface.

High-Pressure Hose

The pressure washer includes a 1/4-inch high-pressure hose designed to provide flexibility and convenient working reach.

CRAFTSMAN’s official listing identifies a 25-foot non-marring, flexible, and abrasion-resistant hose. Lowe’s listings for closely related 49-state production versions have also described a longer 30-foot hose, so the hose length should be matched to the exact model and package being sold. For model CMXGWFN061294, the specifications table lists a 25-foot hose.

The hose should be inspected before every use for:

• Cuts
• Abrasion
• Bulges
• Cracked outer covering
• Damaged fittings
• Leakage
• Heat damage

A damaged high-pressure hose should be replaced rather than repaired with tape or clamps.

Professional-Style Spray Gun and Lance

The included spray gun provides trigger-controlled water flow, while the extension lance positions the nozzle farther from the operator.

The gun should be held securely with both hands when high-pressure spraying begins. Pressure reaction can cause the lance to move suddenly, particularly when using the 0-degree or 15-degree nozzle.

The trigger lock should be engaged whenever the machine is not actively spraying.

Never direct the spray toward:

• People
• Animals
• Hands or feet
• Electrical outlets
• Power lines
• Glass at close range
• Fuel containers
• The pressure washer’s engine
• Fragile materials

High-pressure water can cause serious injury even when the wound appears small.

Powder-Coated Steel Frame

The pressure washer is built around a steel frame with a powder-coated finish.

The frame supports and protects the engine, pump, detergent tank, and accessory components. Powder coating helps resist scratches and corrosion caused by normal outdoor use.

The frame should be rinsed and dried after exposure to:

• Road salt
• Fertilizer
• Pool chemicals
• Detergent
• Coastal air
• Mud
• Corrosive residue

Damage to the powder coating should be repaired before rust spreads.

12-Inch Never-Flat Wheels

Two 12-inch never-flat wheels help move the washer around a home or work area.

Never-flat wheels do not require air-pressure checks and cannot be punctured like pneumatic tires. Their large diameter improves movement across:

• Driveways
• Sidewalks
• Patios
• Grass
• Gravel
• Uneven outdoor surfaces

The pressure washer should not be pulled by the hose or spray gun. Use the frame handle when repositioning the unit.

Fold-Down Handle and Compact Storage

The handle can be folded down on applicable versions to reduce the pressure washer’s storage height.

This makes the unit easier to store in:

• Garages
• Sheds
• Workshops
• Utility rooms
• Vehicle storage areas

The engine should be completely cool before the handle is folded or the unit is placed into storage.

The machine should be stored upright in a clean, dry location.

Avoid directing high pressure at:

• Paint chips
• Window seals
• Electrical connectors
• Cameras and sensors
• Tire sidewalls at close range
• Decals
• Emblems
• Damaged trim
• Engine-compartment electronics

The 0-degree nozzle should not be used for vehicle washing.

Water-Supply Requirements

A standard garden hose should provide enough water to meet the machine’s 2.4 GPM operating requirement.

For reliable performance:

• Use a hose with sufficient internal diameter.
• Keep the hose as short as practical.
• Fully open the water valve.
• Remove kinks and restrictions.
• Clean the inlet screen.
• Do not use a collapsing or damaged hose.
• Do not draw water from an unpressurized tank unless the pump is designed for it.

Low inlet flow may cause pulsing pressure, pump noise, overheating, and damage.

Winter and Long-Term Storage

Water remaining inside the pump, hose, and spray gun can freeze and expand.

Before freezing temperatures:

• Shut down the engine.
• Disconnect the garden hose.
• Release system pressure.
• Drain the spray gun and hose.
• Use an approved pump-protection product.
• Store the unit in a frost-protected area.
• Stabilize or drain the gasoline as instructed.
• Change engine oil if required.
• Clean and dry the machine.

Freeze damage is commonly excluded from pressure-washer warranty coverage.

Important Safety Information

The pressure washer must only be operated outdoors in a properly ventilated area.

Gasoline engines produce carbon monoxide, an invisible and odorless gas that can cause serious injury. Never operate the pressure washer inside:

• A home
• A garage
• A shed
• A basement
• A trailer
• A vehicle
• An enclosed or partially enclosed workspace

Keep the engine exhaust directed away from occupied buildings, doors, windows, and ventilation openings.

High-pressure water can penetrate skin and cause serious injury. Never place hands near a leaking hose, fitting, spray gun, or nozzle while the system is pressurized.

The engine, muffler, pump, and exhaust remain hot after operation. Allow the machine to cool before refueling, transporting, servicing, or storing it.
