Using The High Pressure Hose; Washing With Detergent; Rinsing With The Pressure Washer; Storing Pressure Washer After Use - Black Max BM80919A Operator's Manual

USING THE HIGH PRESSURE HOSE

The high pressure hose features an outer covering that pro-
vides strength to the hose. If the outer covering becomes
damaged, the hose must be replaced immediately. Do not
use a high pressure hose if the outer covering is damaged.
To prevent damage to the outer covering:
 Inspect the hose before every use.
 Fully unwrap and straighten hose before use.
 Do not allow the high pressure hose to be kinked.
 Keep hose away from hot surfaces and sharp edges.
 Do not pull unit by high pressure hose.
 Do not allow hose to be crushed or wrapped around
objects.

WASHING WITH DETERGENT

See Figure 17 - 19.
As sold, this unit is designed for use with "downstream" pres-
sure washer detergents. To convert for use with "upstream"
detergents, contact an authorized customer service center
for more information.
Use only detergents designed for pressure washers; house-
hold detergents, acids, alkalines, bleaches, solvents, flam-
mable material, or industrial grade solutions can damage
the pump. Many detergents may require mixing prior to use.
Prepare cleaning solution as instructed on the solution bottle.
Always test in an inconspicuous area before beginning.
 Remove the cap from the detergent container and pour
detergent in the container. Replace cap on container.
NOTE: The machine setting of this unit is 20:1, which usu-
ally allows the use of 1 gallon pressure washer detergent
without further dilution. Check your detergent instructions
to be sure additional dilution is not necessary.
 Install 6-in-1 Change-Over Nozzle (if necessary). Rotate
the spray selector on the nozzle to either the short range
detergent ( ) or long range detergent ( ) setting.
 Squeeze the trigger and wait approximately 5 seconds
for the detergent to appear.
 Spray the detergent on a dry surface using long, even,
overlapping strokes. To prevent streaking, do not allow
detergent to dry on the surface.
NOTE: To use a detergent bottle, open the detergent container
cap. Next, remove the filter from the end of the detergent
injection hose then slide the hose out of the cap. Place the
detergent injection hose filter back on the hose and place
the hose in the bottom of the bottle.
For long range detergent application:
With the nozzle installed on the spray wand and the engine
shut off, rotate the spray selector to the long range detergent
[ ] setting.

OPERATION

For short range detergent application:
With the nozzle installed on the spray wand and the engine
shut off, rotate the spray selector to the short range deter-
gent [ ] setting.
Before shutting off the engine:
 Place the detergent injection hose in a bucket of clean
water.
 Flush for 1 - 2 minutes (spray clear water through the
spray wand).
 Shut off the engine.
NOTE: Shutting OFF ( O ) the engine will not relieve pressure
in the system. Pull trigger to release water pressure.

RINSING WITH THE PRESSURE WASHER

 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.
 Select the right nozzle setting for the job. See the chart
on the previous page for selecting the appropriate nozzle
setting.
 Start at the top of the area to be rinsed and work down,
overlapping the strokes.
MOVING THE PRESSURE WASHER
See Figure 20.
NOTE: Never lift or carry this product using the moving
handle and never place the unit in any position other than
upright on its wheels.
 Turn the pressure washer off.
 Tilt the machine toward you slightly until it balances on
the wheels then roll the machine to the desired position.
Do not tilt forward or sideways when moving.

STORING PRESSURE WASHER AFTER USE

See Figure 21.
You must pull the trigger to release water pressure before
attempting to disconnect the nozzle or high pressure hose
for storage. Shutting off engine will not relieve pressure in
the system.
To change the position of the handle for easier storage, lower
the lock levers on each side of the handle. Move the handle
to the desired storage position, then return the lock levers
to the locked position.
NOTE: The teeth of the handle cogs must be intertwined to
allow the handle to lock.
For long term storage, see Long-Term Storage of the Pres-
sure Washer in the Maintenance section of this manual.
