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. Air Filter Restriction Indicator. If pop-up indicator is red, filter is clogged
and element must be cleaned or changed and indicator reset.
During warm-up period, check:
* 2. Heater, defroster and windshield wiper.
* 3. Operating lights and rotating beacon.
4. Voltmeter-should show 13.5 to 14 volts.
When engine warms to operating range, check:
5. Service brake and parking brake.
6. Forward and reverse travel.
7. Steering (stop to stop in both directions) with engine at low idle.

9. Horn and back-up alarm. Must be audible from inside operators cab with
engine running.
10. All boom and attachment functions - operate smoothly and correctly.
11. 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
block 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
indicator reaches red area).
