1) If any hose damage is found, replace hose immediately.
2) Remove gun from water with system at operating pressure and trigger in the
closed or “OFF” position. If water is leaking out of barrel or handle, the gun
trigger valve is worn and should be replaced.
3) The initial oil change is after 50 hours of operation
. See pump manufacturer’s
literature in the Appendix for additional recommendations.
6.2 Pump Service
The high pressure water pump requires minimal maintenance. The pump oil level
should be checked on a regular basis. The pump crankcase with Gear box holds
9 liters (304 US fluid ounce), of SAE 80W 90 viscosity non-detergent oil. See
pump manufacturer’s literature found in the
APPENDIX
for further information.
