Operating Instructions
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 po-
tential accident by knowing the employer's safety re-
quirements and all necessary job site regulations, as
well as use and care of the safety equipment on the
KOMATSU 530M Haulpak Truck.
Only qualified operators or technicians should attempt
to operate or maintain the 530M 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 haz-
ard.
• 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 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 opera-
tor 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.
If problems or potential problems are found during the
''walk-around'', be sure to notify maintenance. Vehicle
breakdowns and UNSCHEDULED downtime and loss
of production can be reduced.
OPERATING INSTRUCTIONS
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 (see illustration, next
page). While performing the walk around inspec-
tion, visually inspect all lights and safety equip-
ment for external damage from rocks or misuse.
Make sure lenses are clean and unbroken.
2. Move behind the front of the left front tire, inspect
the hub and the oil disc brake assemblies for leaks
and any abnormal conditions.
Check that all suspension attaching hardware is
secure and inspect 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.
Check that the engine oil filters or oil lines to filters
are not leaking.
4. Inspect fan and air conditioner belts for correct
tension, obvious wear, and tracking. Inspect fan
guard for security and condition.
5. 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 ''bub-
bles'' and that inflation appears to be correct.
6. 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 the tie-rod pivots and steer-
ing cylinder for proper greasing, and for security
of all parts. Inspect for any hydraulic leaks.
7. Inspect sight glass for transmission oil level.
Check pumps on front of transmission for leakage
and that all parts are secure.
8. Move to the side of the hydraulic tank and check
the hydraulic fluid level for both the hydraulic tank
and brake cooling oil. Oil should be visible in sight
glass with engine stopped and body down.
9. Move on around the hydraulic tank and in front of
the rear dual tires, inspect the hoist cylinder for
any damage and leaks.
Inspect both upper and lower hoist cylinder pins
for security, and for proper greasing.
