7-18 How to Perform Planned Maintenance
Functional Tests
You will start the engine to complete the functional tests, so be sure
that:
• The automatic parking brake is applied.
• Directional control is in NEUTRAL.
• Forks are fully lowered to the floor or ground
• All controls are in neutral or other correct position
• You are familiar with the safety procedures given in Section
4, “Operating Procedures,” in this manual.
As you test the following components, be sure they are properly
mounted and working correctly.
Horn
Press the horn button to check horn function. If the horn or any other
part does not operate, report the failure and have it repaired before
the truck is put into operation.
Neutral Start Switch
Check the operation of the neutral start switch by placing the
direction control lever in FORWARD or REVERSE and turning the
key switch to START position. The starter must not engage until the
direction control lever is moved to the NEUTRAL position.
Hour Meter
Start the engine and let it warm up until it runs evenly and
accelerates smoothly when you push on the accelerator pedal.
Check the hour meter for operation with the engine running. Write
the hour meter reading on the PM report form. Report any
malfunction or damage.
Indicator Lights
Check that all lights are functioning and indicate normal truck
operation as described in Section 3, “Operator Compartment and
Controls,” in this manual.
