GENERAL OPERATIONGENERAL OPERATION
Daily Inspection
1.
Always set the parking brake, shut off power
unit engine, remove the ignition key, and ensure
all moving parts have come to a complete stop
before inspecting components, or attempting
any repair or adjustment.
Park the power unit on a level surface, with the
engine shut off and all fl uids cold.
2. Perform a visual inspection of the power unit.
Look for loose or missing hardware, damaged
components, or signs of wear.
3. Inspect the ROPS structure and seat belt for
damage or signs of wear.
4. Inspect the battery, electrical connections, and
lights.
5. Ensure parking brake tension is properly adjusted.
6. Inspect hydraulic hoses, hydraulic fi ttings, and
fuel lines to ensure tight, leak free connections.
7. Inspect belts for damage or excessive wear. Ser-
vice as required.
8. Check the power unit’s engine oil level, hydrau-
lic oil level, coolant level (if equipped), and fuel
level. Add fl uid or service as required.
9. Ensure the radiator screen (if equipped), air
cleaner, and engine compartment are clean.
10. Check tires for proper infl ation.
11. Test the operator safety interlock system.
Starting The Engine
CAUTION
Allow time for hydraulic oil to circulate before operat-
ing the power unit. Severe damage could result to the
hydraulic system if adequate warm up isn’t allowed.
Warm up time is increased in colder weather.
CAUTION
Do not use ether or starting fl uids. Use of starting
fl uids in the air intake system may be potentially
explosive or cause a runaway engine condition.
Use of starting fl uids could result in engine dam-
age and/or personal injury.
The 4500 is equipped with an interlock system for
operator safety. The safety interlock system requires
the parking brake to be engaged and the SDLA
lever to be in the neutral position.
1. Turn the fuel shut-off valve to the On position.
2. Turn the battery disconnect switch to the On
position.
Follow the listed procedure for your engine to start
the power unit engine.
