DO NOT PERFORM ANY MAINTENANCE PROCEDURES
WHILE THE EqUIPMENT IS RUNNING. MOVING PARTS AND
HOT COMPONENTS MAY CAUSE PERSONAL INjURY OR
DAMAGE TO COMPONENTS.
This section of your machine manual may very well be the
most important section of the manual that you read. The proper
care and maintenance of your El Diablo truck mount is essential
for a safe and reliable long life to your investment.
Engine
Check the engine oil level daily when the engine is turned
off and is in a level position. The oil level should be between the
upper limit and the low limit marks on the dipstick. Operating
the engine with improper oil level can cause engine damage
that is not covered under warranty.
Change the oil after the first 20 hours and then every 100
hours thereafter. Use 10 W-30 with an API SERVICE CATEGO-
RY SJ or higher motor oil (see Kohler owners manual). The
engine holds approximately 2 US qts with an oil filter change. . It
is recommended that the oil be warm so it will drain more quickly
and efficiently.
Change the oil filter at least every 200 hours. Use only a
genuine Kohler oil filter or a filter of equivalent quality specified
for your engine model. Check the air filter every 50 hours and
replace as necessary. Replace the spark plugs every 500 hours.
For more specific engine maintenance procedures see the
Kohler Engine Owners Manual. Use only clean, fresh unleaded
gasoline.
Blower
The El Diablo uses a Roots URI-J DSL blower that is splash
lubricated by gear oil on both the front and back of the blower.
There are sight gauges on the side of each gear case for check-
ing the oil level. The gear boxes are filled with ROOTS SYN-
THETIC OIL. Use only ROOTS SYNTHETIC OIL to maintain
optimum performance. The gear oil should be changed after
the first 100 hours of operation, then every 1000 hours there-
after. To drain the oil, remove the drain plug in the bottom of the
gear case and allow the oil to drain out. It is recommended that
the oil be warm so it will drain more quickly and efficiently. To
refill the gear case, remove the top plug and fill until the oil
reaches the middle of the oil sight gauge on the side of the gear
case. The front and rear gear case must be serviced individual-
ly.
At the end of each working day, lubricate the lobes in the
blower by spraying WD-40 (or equivalent) for 5 to 10 seconds
into the Blower Lube located on the front panel of the
machine.(
Note:
When spraying the WD 40 the engine should be
at operating speed and a vacuum load applied by blocking off
the vacuum port on the waste tank or the vacuum hose if it is still
connected to the waste tank.) If the blower is going to be shut
down for an extended time, it is especially important that this be
done to protect the lobes from rusting.
Cat Pump
The crank case on the Cat Pump is filled with special CAT
PUMP CRANKCASE OIL. The oil should be changed after the
first 50 hours of operation then every 500 hours thereafter. Use
only CAT PUMP CRANKCASE OIL to maintain optimum per-
formance. The oil level should be at the middle to the top of the
red dot in the oil sight gauge located on the pump housing.
Belt and Coupler
Belt tension is adjusted by first removing the belt guard.
Then loosen the tensioner mounting bolt. Move the tensioner
away from the pump to increase belt tension. Tighten the
mounting bolts. Reinstall the belt guard.
A spare belt is already installed at the factory. To install a
new spare belt or to replace the coupler sleeve, loosen the ten-
sioner as previously described above, and then loosen the two
set screws in the engine coupling flange. The flange will slide on
the shaft to open up a gap in the coupler assembly to allow a
new belt or coupler sleeve to be installed.
