included with the pressure washer. This kit includes
replacement o-rings, rubber washer and water inlet filter.
Refer to the instruction sheet provided in the kit to
service your unit's o-rings.
WARNING
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 leaking connections with sealant of any
kind. Replace o-ring or seal.
Pump Oil Maintenance
This model does not require any pump maintenance.
The pump is pre-lubricated and sealed, requiring no
additional lubrication for the life of the pump.

Oil
Oil Recommendations
NOTE: When adding oil to the engine crankcase, use
only high quality detergent oil rated with API service
classification SF, SG, SH, SJ or higher. DO NOT use
special additives.
1. Choose a viscosity according to the following table:
5W-30, 10W-30
Synthetic 5W-30, 10W-30
°F
-20
0
20
°C
-30
-20
-10
STARTING TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
NOTE: Synthetic oil meeting ILSAC GF-2, API
certification mark and API service symbol with "SJ/CF
ENERGY CONSERVING" or higher, is an acceptable
oil at all temperatures. Use of synthetic oil does not
alter required oil change intervals.
* The use of multi-viscosity oils (5W-30, 10W-30, etc.)
in temperatures above 40°F (4°C) will result in higher
than normal oil consumption. When using a multi-
viscosity oil, check oil more frequently.
** If using SAE 30 oil in temperatures below 40°F
(4°C), it will result in hard starting and possible engine
bore damage due to inadequate lubrication.
Checking Oil Level
Oil level should be checked prior to each use or at least
every 5 hours of operation. Keep oil level maintained.
1. Make sure pressure washer is on a level surface.
2. Remove oil dipstick and wipe dipstick with clean
cloth. Replace and tighten dipstick. Remove and
and check oil level.
3. Verify oil is at "Full" mark on dipstick. Replace and
tighten dipstick.
