Maintenance - Black Max BM80917 Operator's Manual

WARNING:
When servicing, use only identical replacement parts.
Use of any other parts may create a hazard or cause
product damage.
WARNING:
Always wear eye protection marked to comply with ANSI
Z87.1 during product operation. If operation is dusty, also
wear a dust mask.
WARNING:
Before inspecting, cleaning or servicing the machine, shut
off engine, wait for all moving parts to stop, and discon-
nect spark plug wire and move it away from spark plug.
Failure to follow these instructions can result in serious
personal injury or property damage.
GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, oil, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating oils, etc., come in contact
with plastic parts. Chemicals can damage, weaken or
destroy plastic which may result in serious personal
injury.
Only the parts shown on the parts list are intended to be
repaired or replaced by the customer. All other parts should
be replaced at an authorized service center.
NOZZLE MAINTENANCE
See Figure 22.
Excessive pump pressure (a pulsing sensation felt while
squeezing the trigger) may be the result of a clogged or
dirty nozzle.
 Turn off the pressure washer and shut off the water
supply. Pull trigger to release water pressure.
 Remove the nozzle from the spray wand.
NOTE: Never point the spray wand at your face.
 Using a straightened paper clip or nozzle cleaning tool
(not provided), free any foreign materials clogging or
restricting the nozzle.
 Using a garden hose, flush debris out of nozzle by back
flushing (running the water through the nozzle backwards
or from the outside to the inside).

MAINTENANCE

 Reconnect the nozzle to the spray wand.
 Turn on the water supply and start the engine.
CHECKING/ADDING PUMP LUBRICANT
See Figure 23.
Check the level of the pump lubricant after the first 50 hours
of use. For the remainder of the life of the pressure washer,
the pump lubricant level should be checked after every 100
hours of use.
NOTE: If you notice lubricant leaking out around the pump
seals, take the pressure washer to an Authorized Service
Center for repair.
To check pump lubricant level:
 Set pressure washer on a flat surface.
 Remove pump oil cap/dipstick, wipe dipstick clean, and
re-seat in hole; do not rethread.
 Remove dipstick again and check lubricant level. Lubri-
cant level should fall between the MIN and MAX levels
on the dipstick.
 If level is low, add pump lubricant until the fluid level rises
to the MAX area on the dipstick.
 Replace and secure the pump oil cap/dipstick.
To add pump lubricant:
 Unscrew the pump oil cap/dipstick and remove.
 Using funnel, add universal tractor transmission lubricant
through fill hole.
 Reinstall the oil cap/dipstick and secure.
STORING THE PRESSURE WASHER
See Figure 24.
Store the pressure washer with the gas tank empty by either
draining the tank or running the pressure washer until the
gas runs out. Allow 30 minutes of "cool down" time before
storing the machine. Store in a dry, covered area where the
weather can't damage it.
It is important to store this product in a frost-free area. Always
empty water from all hoses, the pump, and the detergent
bucket before storing.
NOTE: Use of a fuel stabilizer and pump saver will give you
better performance and increase the life of the machine.
Discharge Fuel:
Drain the fuel tank completely. Stored gas can go stale in
30 days.
Engine Lubricant:
Drain the lubricant and replace with fresh, clean lubricant.
NOTE: Consult hazardous waste management guidelines
in your area for the proper way to dispose of used lubricant
and old fuel.
