Black Max BM80917 Operator's Manual page 14

Ethanol (ethyl or grain alcohol) 10% by volume. You
may use gasoline containing up to 10% ethanol by volume.
Gasoline containing ethanol may be marketed under the
name "Gasohol." Do not use E85 fuel.
MTBE (methyl tertiary butyl ether) 15% by volume. You
may use gasoline containing up to 15% MTBE by volume.
Methanol (methyl or wood alcohol) 5% by volume. You
may use gasoline containing up to 5% methanol by volume
as long as it also contains cosolvents and corrosion inhibi-
tors to protect the fuel system. Gasoline containing more
than 5% methanol by volume may cause starting and/or
performance problems. It may also damage metal, rubber,
and plastic parts of the product or your fuel system.
If you notice any undesirable operating symptoms, try another
service station or switch to another brand of gasoline.
NOTE: Fuel system damage or performance problems
resulting from the use of an oxygenated fuel containing more
than the percentages of oxygenates stated previously are
not covered under warranty.
STARTING AND STOPPING THE PRESSURE
WASHER
See Figures 14 - 16.
CAUTION:
Do not run the pump without the water supply connected
and turned on.
Before starting the engine:
 Connect all hoses.
 Check all fluids (lubricant and gas).
 Unroll the high pressure hose from the storage reel.
 Turn on the garden hose then squeeze the trigger to
relieve air pressure; hold the trigger until a steady stream
of water appears.
To start the engine:
 Place the fuel valve lever in the on position.
 If the engine is cold, move the choke lever to the closed
position. As the engine warms, move the choke to the
open position.
If the engine is warm, leave the choke lever in the open
position.
 Move the throttle lever away from the MAX position
(pushed to the right) to about one-third of the way towards
the MIN position (pushed to the left).
 Place the engine switch in the ON ( l ) position.
 Grasp the recoil starter and pull slowly until resistance is
felt. Give the recoil starter a short, brisk pull to start the
engine.
NOTE: If engine does not start after several pulls, depress
trigger to release pressure then repeat normal starting
procedure.
 Move the throttle lever to the MAX position once the
machine is running.
OPERATION
To stop the engine:
 Move the throttle lever to the MIN position.
 Place the engine switch in the OFF ( O ) position.
 Turn the fuel valve lever off.
USING THE SPRAy WAND TRIGGER
See Figures 17 - 18.
For greater control and safety, keep both hands on the
trigger handle at all times.
 Pull back and hold the trigger to operate the pressure
washer.
 Release the trigger to stop the flow of water through the
nozzle.
To engage the lock out:
 Push up on the lock out until it clicks into the slot.
To disengage the lock out:
 Push the lock out down and into its original position.
For the most effective cleaning, the spray nozzle should be
between 8 in. and 24 in. from the surface to be cleaned. If
the spray is too close it can damage the cleaning surface.
SELECTING THE RIGHT NOZZLE FOR THE
JOB
See Figure 19.
Before starting any cleaning job, determine the best nozzle
for the job. Each of the nozzles has a different spray
pattern. The nozzle patterns are: 40º (for gentle rinse),
25º (for general purpose or large surfaces), 15º (for tough
jobs), 0º (for spot cleaning or high-to-reach areas), and the
black nozzle for using detergent.
WARNING:
NEVER change nozzles without locking the lock out on
the trigger handle and NEVER point the wand at your
face or at others. The quick-connect feature contains
small springs that could eject the nozzle with some force.
Failure to heed this may cause personal injury.
Using the quick-connect collar, changing nozzles is easy.
To connect a nozzle to the trigger handle:
 Turn off the pressure washer and shut off the water
supply. Pull trigger to release water pressure.
 Engage the lock out on the trigger handle by pushing up
on the lock out until it clicks into the slot.
 Pull back the quick-connect collar.
 Push the nozzle into place in the spray wand.
 Push the collar forward so that the nozzle is secured
properly. Check to see that the nozzle is secure.
To disconnect a nozzle from the trigger handle once the
cleaning job is complete:
 Turn off the pressure washer and shut off the water
supply. Pull trigger to release water pressure.
