MAINTENANCE
Check and Clean Inlet Screen
Examine the screen on the water inlet. Clean it if the
screen is clogged or replace it if screen is damaged.
Check High Pressure Hose
The high pressure hose can develop leaks from wear,
kinking, or abuse. Inspect the hose each time before using
it. Check for cuts, leaks, abrasions or bulging of cover,
damage or movement of couplings. If any of these
conditions exist, replace the hose immediately.
3400 PSI Pressure Washer
The high pressure stream of water that this
equipment produces can pierce skin and its
underlying tissues, leading to serious injury and
possible amputation.
• NEVER repair high pressure hose. Replace it.
• Replacement hose rating MUST exceed maximum pressure
rating of unit.
Check Detergent Siphoning Tube
Examine the filter on the detergent tube and clean if
clogged.The tube should fit tightly on the barbed fitting.
Examine the tube for leaks or tears. Replace the filter or
tube if either is damaged.
Cleaning Detergent Siphoning Tube
If you used the detergent siphoning tube, you must flush it
with clean water before stopping the engine.
1. Place chemical injection siphon/filter in a bucket full of
clean water.
2. Attach black low pressure spray tip.
3. Flush for 1-2 minutes.
4. Shut off engine.
IMPORTANT: Simply shutting OFF engine will not
release pressure in the system. When the engine has
shut down, squeeze the trigger on the spray gun to
relieve the pressure in the hose.
Check Gun and Nozzle Extension
Examine the hose connection to the spray gun and make
sure it is secure.Test the trigger by pressing it and making
sure it "springs back" into place when you release it. Put
the safety latch in the ON position and test the trigger.You
should not be able to press the trigger.
Check In-Line Filter
Refer to Figure 10 and service the in-line filter if it
becomes clogged, as follows:
