A CAUTION decal is attached below the hydraulic tank
oil level sight gauge. Check level with body down,
engine stopped, and key switch "Off". Add oil per filling
instructions, if oil level is below top of sight glass.
A warning plate is attached to the hydraulic tank to
inform technicians that high pressure hydraulic oil is
present during operation. When it is necessary to open
the hydraulic system, be sure engine is stopped and
key switch is "Off" to bleed down hydraulic pressure.
There is always a chance of residual pressure being
present. Open fittings slowly to allow all pressure to
bleed off before removing any connections.
Any operating fluid, such as hydraulic oil, escap-
ing under pressure can have sufficient force to
enter a person's body by penetrating the skin.
Serious injury and possibly death may result if
proper medical treatment by a physician familiar
with this injury is not received immediately.

A wheel motor oil level decal is attached to the gear
cover on both electric wheel motors. This decal
stresses the fact that the truck must be on a level
surface and parked for 20 minutes prior to checking
the oil level. This is necessary in order to get an
accurate reading.
A decal plate is located on the frame near the left hoist
cylinder which provides the operator or technician with
the hook-up procedure for dumping a loaded, disabled
truck, by using a functional truck for hydraulic power.
Refer to the Section "L" for additional instructions for
using this procedure.
Warning decals are applied to both brake accumula-
tors located inside the brake system cabinet behind
the operator cab. These decals remind servicing tech-
nicians to be sure to close the accumulator drain
valves after they have been opened to bleed brake
pressure. It further warns not to over-tighten the drain
valves to prevent damage to the valve seat(s).
