LOCATED IN THE BACK OF THIS MANUAL. THIS INSPECTION IS A DAILY
REQUIREMENT BEFORE OPERATING THIS MACHINE.
The safety, efficiency and service life of your handler will be increased by
performing the operational checks listed below. Items preceded by an asterisk
(*) are optional and may not be furnished on your machine.
Before entering the operator’s cab, check:
1. Engine oil level.
2. Hydraulic oil level.
3. Air Filter Restriction Indicator. If needle is in red area, filter is clogged
and element must be cleaned or changed.
During warm-up period, check:
* 4. Heater, defroster and windshield wiper.
* 5. Operating lights and rotating beacon.
6. Voltmeter-should show 13.5 to 14 volts.
When engine warms to operating range, check:
7. Transmission fluid level.
8. Service brake and parking brake.
9. Forward and reverse travel.
10. Each of the gear ranges.
11. Steering (in both directions) with engine at low idle. Check in each
steering mode.
12. Horn and back-up alarm. Must be audible from inside operators cab
with engine running.
13. All boom and attachment functions - operate smoothly and correctly.
14. Hydraulic Filter Condition Indicator - observe engine coolant
temperature gauge after starting normal operation. When needle has
been in operating range for an hour or so, stop handler in a safe
area, apply parking brake, lower forks fully, shift forward/reverse lever
to “Neutral” position and chock wheels. With engine running at full
throttle, have an assistant check the Hydraulic Filter Condition
Indicator. When bar gauge is in red area, filter is clogged and hydraulic
oil is bypassing filter. Filter element must be changed before reaching
bypass condition (change before needle reaches red area).
Complete all required maintenance before operating unit.
