PUMP OIL MAINTENANCE:
CHANGING PUMP OIL
Change oil after first 50 hours of operation and then every 200 hours or 3 months, which ever occurs first.
Note: When changing pump oil, use only high quality non-detergent SAE30 oil. Use no special additives.
CHANGE PUMP OIL AS FOLLOWS:
•
Clean area around brass oil drain plug at bottom of pump.
•
Remove oil drain plug. Drain oil completely into approved container.
•
When oil has completely drained, install oil drain plug and tighten firmly.
•
Clean area around pump breather plug. Remove breather and fill pump with 600ml of recommended oil.
Make sure it shows halfway on sight glass, add more if necessary.
•
Wipe up any spilled oil.
Used motor oil may cause skin cancer if repeatedly left in contact with
the skin for prolonged periods. Although this is unlikely unless you
handle used oil on a daily basis, it is still advisable to thoroughly wash
your hands with soap and water as soon as possible after handling
used oil.
Please dispose of used motor oil in a manner that is compatible with the environment. We suggest you take it in a
sealed container to your local service station or recycling center for reclamation. Do not throw it in the trash or
pour it on the ground.
LONG-TERM STORAGE:
Before you store the pressure washer, make sure you do the following:
1. Remove fuel from engine or add fuel stabilizer, such as “Sta-Bil” to the gasoline to prevent gumming,
and operate unit normally for five minutes.
2. If adding stabilizer, connect water supply and high pressure hose to pump.
3. Ensure water supply is turned on, start pressure washer and depress gun trigger to avoid running the
unit in the “by-pass mode.”
5. Disconnect spark plug wire and remove spark plug. Pour one teaspoon of engine oil into the spark plug
hole. Place a rag over spark plug hole and pull rope slowly several times to lubricate cylinder, replace
spark plug and lead.
6. Protect the high pressure hose, gun and wand from damage (such as being stepped on or run over).
TO PREVENT INTERNAL CORROSION OR FREEZING:
Items needed:
100cm piece of garden hose or equivalent and antifreeze (approximately 200 m
ℓ
.)
1. To winterize the pressure pump, prevent the engine from starting by disconnecting the spark plug wire
from the engine and remove high pressure hose from the pump. Add automotive antifreeze corrosion
inhibitor through the water inlet, place the garden hose direct into the anti freeze container. Pull engine
rope several times until antifreeze comes out of high pressure outlet connector. You have now
displaced the water in the pump with corrosion inhibitor.
2. Remove all water from high pressure hose, gun, and wand. To do so, disassemble high pressure hose
from gun. Drain all water from hose. Hold gun/wand assembly in a vertical position with the nozzle
pointing down, and pull gun trigger to remove any water.
