After Engine Has Started - Komatsu 830E-AC Shop Manual

AFTER ENGINE HAS STARTED

1. Become thoroughly familiar with steering and
emergency controls. After the engine has been
started, do not accelerate engine speed or
drive truck until low pressure and warning sys-
tems are normal, and the coolant temperature
is at least 71°C (160°F).
2. Test the truck steering in extreme right and left
directions. If the steering system is not operat-
ing properly, shut the engine off immediately.
Determine the steering system problem and
have it repaired before resuming operation.
3. Operate each of the truck's brake circuits at
least twice prior to operating and moving the
truck. These circuits include individual activa-
tion from the operator's cab of the service
brake, parking brake, and brake lock. With the
engine running and with the hydraulic circuit
fully charged, activate each circuit individually.
To operate the park brake, the directional con-
trol lever must be in the PARK position. If any
application or release of any brake circuit
appears sluggish or improper, or if warning
alarms are activated on application or release,
shut the engine off and notify maintenance per-
sonnel. DO NOT operate the truck until the
brake circuit in question is fully operational.
4. Check the gauges, warning lights and instru-
ments before moving the truck to ensure proper
system operation and proper instrument func-
tioning. Pay special attention to braking and
steering circuit hydraulic warning lights. If warn-
ing lights come on, shut off the engine immedi-
ately and determine the cause.
5. Ensure the headlights, work lights and taillights
are in proper working order. Good visibility may
prevent an accident. Check operation of the
windshield wipers.
Additional Guidelines
1. When the truck body is raised, DO NOT allow
anyone beneath it unless the body-up retaining
cable is in place.
2. DO NOT use the fire extinguisher for any pur-
pose other than putting out a fire! If an extin-
guisher is discharged, report the occurrence so
the used unit can be refilled or replaced.

MACHINE OPERATION SAFETY
CAUTIONS
After the truck engine is started and all systems are
functioning properly, the operator must follow all local
safety rules to ensure safe machine operation.
If any of the red warning lights illuminate or if any
gauge reads in the red area during truck opera-
tion, a malfunction is indicated. Stop the truck as
soon as safety permits, and stop the engine.
Have the problem corrected before resuming
truck operation.
The truck is equipped with "slip/slide" control. If
this function should become inoperative, operat-
ing the truck with stalled or free spinning wheel
motors may cause serious damage to wheel
motors! If the truck does not begin to move
within ten seconds after depressing the throttle
pedal (directional control lever in a drive posi-
tion), release the throttle pedal and allow wheels
to regain traction before accelerating again.
General Safety and Operating Instructions
3. DO NOT allow unauthorized personnel to ride
in the truck. DO NOT allow anyone to ride on
the ladder or outside of the truck cab. Passen-
gers must be belted into the passenger seat
during travel.
4. DO NOT leave the truck unattended while the
engine is running. Move the directional control
lever to PARK, then shut the engine off before
getting out of the cab.
1. Always look to the rear before reversing the
truck. Watch for and obey the ground spotter's
hand signals before traveling in reverse. Sound
the horn (three blasts). The spotter will have a
clear view of the total area at the rear of the
truck.
2. Operate the truck only while properly seated
with seat belt fastened. Keep hands and feet
inside the cab compartment while the truck is in
operation.
