A03020 General Safety and Operating Instructions A3-19
OPERATING INSTRUCTIONS
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 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
provided for the operator such as hard hat,
safety shoes, safety glasses or goggles. There
are some conditions when protective hearing
devices 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 Inspec-
tion
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
inspection 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 illustra-
tion, next page), and move in a counter-clockwise
direction, front-to-rear, across the rear, and continu-
ing 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 direc-
tion 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.
1. Start at left front of truck. While performing the
walk around inspection, visually inspect all
lights and safety equipment for external dam-
age from rocks or misuse. Make sure lenses
are clean and unbroken.
Empty the dust pans on the left side air cleaner
assemblies.
2. Move behind the front of the left front tire,
inspect the hub and brake assemblies for leaks
and any abnormal conditions.
Check that all suspension attaching hardware
is secure and inspect mounting key area for
evidence of wear. Check that the suspension
extension (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 fan and 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 lugs/wedges to be sure all are tight
and complete. Check tires for cuts, damage or
“bubbles” and that inflation appears to be cor-
rect.
7. Move behind the rear of the front wheel, inspect
for leaks at hub or brakes or any unusual condi-
tions. Inspect suspension hardware to be sure it
is all in place. Inspect live end of steering cylin-
der for proper greasing, and for security of all
parts. Inspect for any hydraulic leaks.
8. Swing hydraulic inspection ladder down. Inspect
sight glass on hydraulic tank. With engine
stopped and body down, hydraulic fluid must be
visible in upper sight glass. If not, oil must be
added. Be sure ladder is in the up position and
is secure.
