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 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, and use and care of the safety
equipment on the truck. Only qualified operators or
technicians should attempt to 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 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.
WALK AROUND INSPECTION
At the beginning of each shift, a careful walk around
inspection should be performed before attempting to
start the engine. 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 the
illustration on the next page) and move in a
counterclockwise
direction.
across the rear, and continue 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
direction before every shift, many potential problems
may be avoided or scheduled for maintenance.
Unscheduled downtime and loss of production can be
reduced as a result.
Local work practices may prevent an operator from
performing all tasks suggested here. To the extent
permitted, the operator should follow this routine.
OPERATING INSTRUCTIONS

front-to-rear,
Operating Instructions - Section 30
High voltage may be present on this truck! DO
NOT open any electrical cabinet doors on this
truck while the engine is running. Never climb on
any power cables or use power cables for
handholds or footholds unless the engine has
been shut down and the system has been verified
to be at "rest".
1. Start at left front of truck. Visually inspect all
lights and safety equipment for damage. Make
sure that the lenses are clean and unbroken.
Empty the dust collectors on the left side air
cleaner assemblies. (A ladder may be neces-
sary to reach the air cleaners.) Make sure that
the battery box covers are in place and secure.
2. Move in front of the left front tire. Inspect the
hub and brake assemblies for leaks and any
abnormal conditions.
3. Make sure that all suspension mounting
hardware is secure. Inspect the mounting key
area for evidence of wear. Make sure that the
suspension extension (exposed piston rod) is
correct and that there are no leaks.
4. Make sure that the anchor end of the steering
cylinder is secure and properly greased.
5. With the engine stopped, check the engine oil
level. Use the service light, if necessary.
6. Inspect the air conditioner belts for correct
tension, obvious wear, and tracking. Make sure
that the fan guard is secure and in good
condition. When leaving this point, turn off the
service light if used.
7. Move outside of the front wheel. Make sure that
all of the mounting nuts/studs are in place and
tight. Check the tires for cuts, damage, or
bubbles. Check for evidence of incorrect tire
inflation.
8. Move in behind the front wheel. Make sure that
the steering cylinder is properly greased and
the mounting hardware is tight. Check the
suspension mounting hardware and suspension
extension. Make sure that the suspension
protective boot is in good condition. Inspect the
hub and brakes for any unusual conditions.
Check the entire area for leaks.
