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 power unit on a level surface, with the
engine shut off and all fluids 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 fittings, and
fuel lines to ensure tight, leak free connections.
7. Inspect belts for damage or excessive wear.
Service as required.
8. Check the power unit’s engine oil level, hydraulic
oil level, coolant level, and fuel level. Add fluid or
service as required.
9. Ensure the radiator screen and engine compart-
ment are clean. Inspect the air filter restriction
gauge.
10.
Check tires for proper inflation.
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 fluids. Use of starting
fluids in the air intake system may be potentially
explosive or cause a runaway engine condition.
Use of starting fluids could result in engine dam
-
age and/or personal injury.
The 3400 is equipped with an interlock system for
operator safety. The safety interlock system requires
the parking brake to be engaged.
1.
Turn the fuel shut-off valve to the On position.
2. Turn the battery disconnect switch to the On
position.
3. Move the throttle lever to just past the half
throttle position.
4. Turn the ignition key to the run position to activate
the glow plugs for preheating the combustion
chamber. When the glow plug indicator light turns
off, the engine is ready to start. If the engine is
at operating temperature, the engine does not
need to be preheated. If the ambient temperature
is below 23° F (-5° C), the preheating cycle may
need to be repeated prior to starting.
5.
CAUTION
Do not run the electric starter continuously for
more than 10 seconds. If the engine does not
start right away, wait 30 seconds and try again.
Turn the ignition key to the start position and
hold to engage the starter. Release the key
when the engine starts. NOTE: if engine fails to
start, refer to the troubleshooting section.
6. The engine and hydraulic oil must be warmed to
operating temperature before operations. Allow
the unit to run at approximately 1800 rpm until
the hydraulic filter is warm to touch. The hydrau
-
lic filter is located at the right rear of the front
frame, below the front transaxle neutral link.
