STARTUP
Always
use this startup procedure to ensure that the
unit
is
started safely and properly
.
1.
Check oil levels.
Engine:
Add SAE 30 or 10W–30 weight detergent oil
as
necessary
.
Pump:
Add SAE 20 or 30 weight non–detergent oil or
genuine
Cat
R
pump oil as necessary
.
Gear
Reducer (2040 and 2540): Add SAE 90 gear oil
as necessary . The 1535 uses the oil in pump
crankcase.
NOTE:
All
units are equipped with a low–oil sensor that
shuts
the engine of
f if the oil level
falls below a
certain level. If the unit stops unexpectedly ,
check
both the oil and the fuel levels. Check the
oil
level each time the unit is refueled.
2.
Check fuel level.
WARNING
DO NOT
refuel a hot engine. Refueling a hot
engine could cause a fire. Use only fresh, clean
regular or unleaded gasoline. Close the fuel
shutoff
valve during refueling.
3. T
urn on the water supply
.
CAUTION
Never
run the unit dry
. Costly damage to the pump
will result. Always be sure the water supply is
completely
turned on before operating.
4. Trigger the gun until water sprays from the tip
indicating
that the air is purged from the system.
5. Open the fuel shutoff valve. Be sure the spark plug
ignition
cable is pushed firmly onto the
spark plug. On
those
units equipped with an
ignition shutof
f switch,
put
the
switch in the “on” position and put the throttle
in
the “run” position.
6.
Start the engine.
NOTE: For easier starting, have one person start the
pressure
washer while
another person triggers
the
spray gun.
If the engine is cold, completely close the engine
choke.
Grasp the starter rope, brace one foot on the
pressure washer chassis and pull rope rapidly and
firmly. Continue holding the rope as it returns. Pull
and return the rope until the engine starts. In cool
weather,
the
choke may have to be kept closed for 10
to 30 seconds before opening it to keep the engine
running. Otherwise, open the choke as soon as the
engine
starts.
If the engine is warm, leave the choke open, or just
partly close it. Start the engine as described in the
preceding
paragraph. When it starts, be sure to open
the
choke completely
.
CAUTION
On
recoil start engines, never let the starter rope
return by itself. It could jam the recoil system.
7.
ALWAYS
engage the gun’ s trigger safety latch
whenever
you stop spraying, even for a moment, to
reduce the risk of fluid injection or splashing in the
eyes
or on the skin if the gun is bumped or triggered
accidentally.
8.
ALWAYS
observe the following
CAUTIONS
to avoid
costly
damage to the pressure washer
.
CAUTION
DO
NOT
allow
the pressure washer to idle for more
than 10 minutes. Doing so may cause the
recirculating water to overheat and seriously
damage
the pump. T
urn of
f the pressure washer if it
will not be spraying or cleaning at least every 10
minutes. If heated inlet water is used, reduce this
time further.
DO NOT
run the pump dry , which will quickly
damage
the pump. Be sure
the water supply is fully
turned
on before starting the pump.
DO
NOT
operate the pressure washer
with the inlet
water screen removed. This screen helps keep
abrasive sediment out of the pump, which could
clog
or scratch the pump. Keep this screen clean.
DO NOT
pump caustic materials; such materials
may
corrode the pump components.
9. See the chemical injector or sandblaster kit manual
for
detailed cleaning information if these accessories
are
used.
