TRUCK OPERATION
PREPARING FOR OPERATION
The safest trucks are those which have been properly
prepared for operation. At the beginning of each shift,
a careful check of the truck should be made by the
operator before attempting to start 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 should
attempt to operate or maintain the 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 pro-
vided for the operator such as hard hat, safety
shoes, safety glasses or goggles. There are
some conditions when protective hearing de-
vices should 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.
At The Truck - Ground Level Walk Around
Inspection
At the beginning of each shift, a careful walk around
inspection of the truck should be made before the
operator attempts engine start-up. A walk around in-
spection is a systematic ground level inspection of the
truck and its components to insure that the truck is safe
to operate before entering the operator’s cab.
Start at the left front corner of the truck (see illustration,
next page), and move in a counter-clockwise direction,
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 taken in sequence, and are repeated
from the same point and in the same direction before
every shift, many potential problems may be avoided,
or scheduled for maintenance. UNSCHEDULED
downtime and loss of production can be reduced.
Local work practices may prevent an operator from
performing all tasks suggested here, but to the extent
permitted, the operator should follow this or similar
routine.
HIGH VOLTAGE MAY BE PRESENT ON THIS
TRUCK! DO NOT OPEN ANY ELECTRICAL CABI-
NET DOORS ON THIS TRUCK WHEN THE ENGINE
IS RUNNING! NEVER CLIMB ON ANY POWER CA-
BLES OR USE POWER CABLES FOR HAND-
HOLDS OR FOOTHOLDS, UNLESS THE ENGINE
HAS BEEN SHUT DOWN AND SYSTEM HAS BEEN
VERIFIED AT “REST”!
1. Start at left front of truck. While performing the
walk around inspection, visually inspect all lights
and safety equipment for external damage from
rocks or misuse. Make sure lenses are clean and
unbroken.
Empty the dust pans on the left side air cleaner
assemblies. Be sure 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. Check front wheel hub oil
sight gauge for oil level.
Check that all suspension attaching hardware is
secure and inspect mounting key area for evi-
dence of wear. Check that the suspension exten-
sion (exposed piston rod) is correct, and that
there are no leaks.
3. With engine stopped, check engine oil level. If
dark, turn on service light.
4. Inspect air conditioner belts for correct tension,
obvious wear, and tracking. Inspect fan guard for
security and condition. When leaving this point,
be sure to turn off service light, if used.
5. Inspect anchor end of steering cylinder for proper
greasing and for security.
6. Move outboard of the front wheel, and inspect
attaching nuts/studs to be sure all are tight and
complete. Check tires for cuts, damage or “bub-
bles” and that inflation appears to be correct.
