Black Max BM80721 Operator's Manual page 19

WARNING:
NEVER remove nozzles without first turning off the
motor, and locking the lock out on the trigger handle.
NEVER point the nozzle at your face or at others. The
quick-connect feature contains small springs that could
eject the nozzle with some force. Failure to follow these
instructions could result in an eye injury or other serious
personal injury.
 To free any foreign materials clogging or restricting the
nozzle, blow out or remove debris with a straightened
paper clip or fine needle.
 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).
 Reconnect the nozzle to the spray wand.
PUMP LUBRICATION
The pump on this unit is lubricated with a sufficient amount
of high grade lubricant for the life of the unit under normal
operating conditions. Therefore, no further lubrication is
required.
PUMP MAINTENANCE
Routinely make a visual inspection of the pump. If you notice
any leaking of lubricant around the pump seals, take the
pressure washer to an authorized service center for repair.
There are no user serviceable parts to the pressure washer
pump. Any attempt to service or alter the pump may damage
the pressure washer and void your product warranty.
