The Campbell Hausfeld PM351377AV Pressure Washer Gun AR Bit 105 2700 PSI is intended to restore proper spray control and trigger operation in suitable pressure washers.

Common symptoms include:

• Trigger not responding properly

• Water leaking from the gun

• Inconsistent spray pressure

• Weak water discharge

• Poor spray control

Trigger Not Responding

Quick Check: Squeeze the trigger and verify that it moves freely without sticking or excessive resistance.

Fix Suggestion: Disconnect the spray gun, inspect the trigger linkage for obstruction and replace the gun if the internal trigger mechanism is worn.

Prevention Tip: Rinse the spray gun after each use to prevent dirt buildup around the trigger.

Water Leaking from the Gun

Quick Check: Inspect the gun body, inlet connection, and outlet fitting for visible leaks while water is flowing.

Fix Suggestion: Replace worn sealing, tighten threaded fittings securely, and inspect the hose connection for proper lubrication.

Prevention Tip: Avoid overtightening fittings and replace damaged seals during routine maintenance.

Weak Water Discharge

Quick Check: Confirm the pressure washer is producing normal pressure and inspect the gun for internal restrictions.

Fix Suggestion: Flush the spray gun with clean water to remove trapped debris and ensure the nozzle.

Prevention Tip: Use clean water and regularly inspect the inlet filter for contamination.

Inconsistent Spray Pressure

Quick Check: Observe whether the spray pattern fluctuates while maintaining constant engine or motor speed.

Fix Suggestion: Inspect the hose for kinks and confirm the spray gun valve opens and closes smoothly without binding.

Prevention Tip: Store the spray gun in a clean, dry location and protect it from impact damage.
