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 before the
operator attempts engine start-up.
1. When walking to and from the truck, BE ALERT,
remain a safe distance from all other machines
even if the operator is visible.
2. Check for any oil or coolant leaks. When checking
coolant in radiator, relieve pressure slowly before
removing radiator cap.
If engine has been running, allow coolant to cool,
before removing the fill cap or draining radiator.
Serious burns may result if coolant is not allowed
to cool.
3. Check tires for cuts, damage or "bubbles". Check
tires for low pressure periodically during shift. If
truck has been run on a "flat", the tire must be
cooled before parking truck inside.
4. Visually inspect all headlights, worklights and tail-
lights and safety equipment for external damage
from rocks or misuse. Make sure lenses are clean.
5. Always use handrails and ladder when mounting
or dismounting the truck. Clean ladder and hand-
rails of any foreign material, such as ice, snow, oil
and mud.
Always mount and dismount the truck facing the
truck. Never attempt to mount or dismount the
truck while it is in motion.
6. Dirt or trash buildup, specifically in the operator's
cab, should be cleared. Do not carry tools or
supplies in cab of truck or on the deck.
7. Insure steering wheel, controls and pedals are free
of any oil, grease or mud.
8. Insure adequate ventilation before start-up if the
truck is in an enclosure. Exhaust fumes are dan-
gerous!
OPERATING INSTRUCTIONS
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.
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 brake assemblies for leaks and any
abnormal conditions.
Check that all suspension attaching hardware
(including the splined nut under the spindle) 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.
Check air cleaner indicator. If the RED area is
showing in the indicator, the air filter must be
cleaned/replaced before operating truck.
4. Inspect fan and air conditioner belts for correct
tension, obvious wear, and tracking. Inspect fan
guard for security and condition.
