After Starting; Warm Up; Run-In Period; Stopping The Engine - Gehl RT175 Operator's Manual

Operation

After Starting

1. Check that charge (F, Fig 41) indicator goes out
after the engine starts.
IMPORTANT:
If the charge and/or the engine oil
pressure indicators do not go out when the engine
is running, shut down the engine immediately and
correct the problem. Damage to the engine may
result if engine is run and the problem is not cor-
rected.
IMPORTANT:
Do not run a cold engine at full
throttle when starting. Stressing a cold engine can
damage the engine. Perform the following warm up
procedure before using the machine after starting.
IMPORTANT:
When the machine is not under
load, do not run the engine at high speed (above
20% of full throttle) for extended periods of time.
Damage to the engine can result.

Warm Up

WARNING
Operating the work hydraulics before the
hydraulics are warmed up is dangerous,
because response will be slow and the machine
might move in unexpected ways. Be sure to
sufficiently warm up the machine before
starting work.
IMPORTANT:
Do not operate the control joysticks
suddenly until the hydraulic oil has reached operat-
ing temperature.
1. After starting, allow the engine to run at low idle
for a minimum of 5 minutes with no load (no
drive, lift, tilt or auxiliary hydraulic functions).
2. Run the engine at 1800 rpm with no load for 5
minutes.
3. Raise the lift arm so the attachment is off the
ground.
4. Extend and retract each of the cylinders several
times with no load.
5. Travel slowly forward and backward several
times.

6. Additionally, in cold weather, tilt the attachment
all the way forward and keep it there for 20-25
seconds. Repeat this step until the attachment tilt
speed is normal.

Run-In Period

The performance and service life of the machine is
heavily dependent on using the machine carefully
during its first 100 operating hours.
• Do not operate machine at the maximum rated
operating capacity.
• Do not run the engine at a high speed for
extended periods of time.
• Increase the load gradually while varying the
engine speed.
• Follow the maintenance schedule. See "Mainte-
nance Schedule" on page 100.

Stopping the Engine

Perform the "Mandatory Safety Shutdown
Procedure" on page 16.
IMPORTANT:
Do not stop the engine at full throt-
tle. Damage to the engine can result. Allow the
engine to idle for approximately 2 minutes before
shutting it off.

After Operation

Park the machine on firm, level ground. Raise
the arm rests/safety bars to apply the parking
brake and lock out the hydraulic controls.
Never leave the engine running if leaving the
machine unattended.
