Operation & Maintenance Manual

STARTING THE ENGINE (DELUXE PANEL, KEYLESS
START (CONT’D)

Procedure (Cont’d)

Figure 55

(ACS)  Select hand control or foot pedal operation (1)
[Figure 55].

OR

(SJC) Select ‘ISO’ or ‘H’ Control Pattern (2) [Figure 55].

Figure 56

Press the PRESS TO OPERATE LOADER Button (1)
[Figure 56] to activate the BICS system and to perform
hydraulic and loader functions. (See Cold Temperature
Starting on Page 27.)

NOTE: (SJC) The pending mode will flash which will

indicate PRESS TO OPERATE LOADER is
required. The light will flash when key is ON
and continue to flash until the PRESS TO
OPERATE LOADER button is pressed and
thereafter it will light solid. If the mode (ISO/H)
is changed while driving, the active mode will
be solid and the pending mode will flash.
When operation of the machine is returned to
neutral, the active mode will then turn off and
the pending mode will continue to flash until
the PRESS TO OPERATE LOADER button is
pressed.

Cold Temperature Starting

If the temperature is below freezing, perform the following
to make starting the engine easier:

Replace the engine oil with the correct type and
viscosity for the anticipated starting temperature.
(See also ENGINE LUBRICATION SYSTEM on
Page 67.)

Make sure the battery is fully charged.

Install an engine heater, available from your Bobcat
loader dealer.

NOTE: The display screen of the Deluxe Panel may

not be immediately visible when the
temperature is below -26° C (-15 ° F). It may
take 30 seconds to several minutes for the
Display Panel to warm up. All systems remain
monitored even when the display is off.

WARMING THE HYDRAULIC / HYDROSTATIC 
SYSTEM

Procedure

IMPORTANT

When the temperature is below -30°C (-20°F),
hydrostatic oil must be warmed before starting. The
hydrostatic system will not get enough oil at low
temperatures and will be damaged. Park the machine
in an area where the temperature will be above -18°C
(0°F) if possible.

I-2007-1285

Let the engine run at least 5 minutes to warm the engine
and hydrostatic fluid before operating the loader.

Figure 57

If the Fluid Pressure Icon (1) [Figure 57]  (Standard
Panel)
 or (2) [Figure 57] (Deluxe Panel) comes ON when
operating the loader (cold), more warm up time is
needed.

STOPPING THE ENGINE

Procedure

Figure 58

Pull the engine speed control fully backward [Figure 58]
to decrease the engine speed.

Let the engine run at idle speed for 5 minutes to let the
turbocharger cool before stopping the engine. 

Figure 59

Turn the key switch to the STOP position (1) [Figure 59]
(Standard Panel) or press the STOP Button (2)
[Figure 59] (Deluxe Panel).

Operation & Maintenance Manual

MONITORING THE DISPLAY PANEL

Figure 60

After the engine is running, frequently monitor the right
instrument panel [Figure 60]  (Standard Panel) or
[Figure 60] (Deluxe Panel) for error conditions.

The associated icon will be ON if there is an error
condition.

EXAMPLE: Engine Coolant Temperature is High

Standard Panel

The Engine Temperature Icon (1) [Figure 60] will be ON.

Press and hold LIGHTS Button for 2 seconds. One of the
following SERVICE CODES will be displayed.

08-10 Engine Coolant Temperature High

08-11 Engine Coolant Temperature Extremely High

Deluxe Panel

The Engine Temperature Icon (2) [Figure 60] will be ON.

The SERVICE CODE will be in the hourmeter/code
display.

In addition, the Deluxe Panel display screen will describe
the extreme condition that can cause damage to the
engine or loader systems [Figure 60].

WARNING and SHUTDOWN

When a WARNING condition exists, the associated Icon
light will come ON and there will be 3 beeps from the
alarm. Be aware that, if this condition is allowed to
continue, there may be damage to the engine or loader
hydraulic systems.

When a SHUTDOWN condition exists, the associated
Icon light will come ON and there will be a continuous
beep from the alarm and the monitoring system will
automatically stop the engine in 10 seconds. The engine
can be restarted to move or relocate the loader.

The SHUTDOWN feature is associated with the following
Icons:

General Warning
Engine Oil Pressure
Engine Coolant Temperature
Hydraulic Oil Temperature
Hydrostatic Charge Pressure

Whenever  STOP appears on the display screen, lower
the lift arms all the way, put the attachment flat on the
ground and stop the engine to prevent damage to the
engine or loader systems.

ATTACHMENTS AND BUCKETS

Choosing The Correct Bucket

NOTE: Warranty is void if non-approved attachments

are used on the Bobcat Loader.

WARNING

Never use attachments or buckets which are not
approved by Bobcat Company. Buckets and
attachments for safe loads of specified densities are
approved for each model. Unapproved attachments
can cause injury or death.

W-2052-0500

The dealer can identify, for each model loader, the
attachments and buckets approved by Bobcat. The buckets
and attachments are approved for Rated Operating
Capacity and for secure fastening to the Bob-Tach™.

The Rated Operating Capacity for this loader is shown on
a decal in the operator cab. (See Machine Rating on
Page 100.)

The Rated Operating Capacity is determined by using a
standard dirt bucket, and material of normal density, such
as dirt or dry gravel. If longer buckets are used, the load
center moves forward and reduces the Rated Operating
Capacity. If very dense material is loaded, the volume
must be reduced to prevent overloading.

Figure 61

Exceeding the Rated Operating Capacity [Figure 61] can
cause the following problems:

Steering the loader may be difficult.

Tires will wear faster.

There will be a loss of stability.

The life of the Bobcat Loader will be reduced.

Use the correct bucket size for the type and density of
material being handled. For safe handling of materials
and avoiding machine damage, the attachment (or
bucket) should handle a full load without going over the
Rated Operating Capacity for the loader. Partial loads
make steering more difficult.
