Truck Operation - Komatsu 830E-AC Shop Manual

PREPARING FOR OPERATION
The safest trucks are those which have been prop-
erly prepared for operation. At the beginning of each
shift, a careful check of the truck must be made by
the operator before starting the engine.
Safety Is Thinking Ahead
Prevention is the best safety program. Prevent a
potential accident by knowing the employer's safety
requirements, all necessary job site regulations, as
well as use and care of the safety equipment on the
truck. Only qualified operators or technicians can
operate or maintain a Komatsu truck.
Safe practices start before the operator gets to the
equipment!
• Wear the proper clothing. Loose fitting clothing,
unbuttoned sleeves and jackets, jewelry, etc.,
can catch on a protrusion and cause a potential
hazard.
• Always use the personal safety equipment
provided for the operator such as hard hats,
safety shoes, safety glasses or goggles. There
are some conditions when protective hearing
devices must also be worn for operator safety.
• When walking to and from the truck, maintain a
safe distance from all machines, even if the
operator is visible.
WALK AROUND INSPECTION
At the beginning of each shift, a careful walk around
inspection of the truck must be performed before the
operator attempts engine start-up. A walk around
inspection is a systematic ground level inspection of
the truck and its components to ensure that the truck
is safe to operate before entering the operator's cab.
Start at the left front corner of the truck (see illustra-
tion, next page), and move in a counter-clockwise
direction. Move front-to-rear, across the rear, and
continuing forward up the opposite side of the truck
to the original starting point.
If these steps are performed in sequence, and are
repeated from the same point and in the same direc-
tion before every shift, many potential problems may
be avoided, or scheduled for maintenance. Unsched-
uled downtime and loss of production can be
reduced as a result.

TRUCK OPERATION

Local work practices may prevent an operator from
performing all tasks suggested here. To the extent
permitted, the operator should follow this or a similar
routine.
High voltage may be present on this truck! DO
NOT open any electrical cabinet doors on the
truck while the engine is operating! Never climb
on any power cables or use power cables for
hand holds or footholds, unless the engine has
been shut off and the system has been verified
as at rest!
General Safety and Operating Instructions
1. Start at left front of the truck. While performing
the walk around inspection, visually inspect all
lights and safety equipment for external dam-
age from rocks or misuse. Ensure lenses are
clean and unbroken.
Empty the dust pans on the left side of the air
cleaners. Ensure the battery box covers are in
place and secure.
2. Move behind the front of the left front tire.
Inspect the hub and brake assemblies for leaks
and any abnormal conditions.
3. Check that all suspension attaching hardware is
secure and inspect the mounting key area for
evidence of wear. Check that the suspension
rod extension is correct, and that there are no
leaks. Ensure the suspension protective boot is
in good condition.
4. Inspect the anchor end of the steering cylinder
for proper greasing and all parts are secure.
5. With the engine stopped, check the engine oil
level. Use the service light if necessary.
6. Inspect air conditioner belts for correct tension,
obvious wear, and tracking. Inspect fan guard
security and condition. When leaving this point,
be sure to turn off the service light, if used.
7. Move outboard of the front wheel. Inspect
attaching lugs/wedges to be sure all are tight
and complete. Inspect the tires for cuts, dam-
age or bubbles. Check tire inflation pressure.
Check sight glass for front wheel oil level.
