Illustration 7

Always use a board or cardboard when you check
for a leak. Leaking fluid that is under pressure can
penetrate body tissue. Fluid penetration can cause
serious injury and possible death. A pin hole leak can
cause severe injury. If fluid is injected into your skin,
you must get treatment immediately. Seek treatment
from a doctor that is familiar with this type of injury.

g00687600

Containing Fluid Spillage

Care must be taken in order to ensure that fluids
are contained during performance of inspection,
maintenance, testing, adjusting and repair of the
equipment. Prepare to collect the fluid with suitable
containers before opening any compartment or
disassembling any component that contains fluids.

Use caution. Avoid inhaling dust that might be
generated when you handle components that contain
asbestos fibers. Inhaling this dust can be hazardous
to your health. The components that may contain
asbestos fibers are brake pads, brake bands, lining
material, clutch plates, and some gaskets. The
asbestos that is used in these components is usually
bound in a resin or sealed in some way. Normal
handling is not hazardous unless airborne dust that
contains asbestos is generated.

If dust that may contain asbestos is present, there
are several guidelines that should be followed:

Never use compressed air for cleaning.

•

Avoid brushing materials that contain asbestos.

•

Avoid grinding materials that contain asbestos.

•

Use a wet method in order to clean up asbestos

•

materials.

A vacuum cleaner that is equipped with a high

Do not touch any part of an operating engine.
Allow the engine to cool before any maintenance is
performed on the engine. Relieve all pressure in the
air system, in the oil system, in the lubrication system,
in the fuel system, or in the cooling system before
any lines, fittings or related items are disconnected.

Coolant

When the engine is at operating temperature, the
engine coolant is hot. The coolant is also under
pressure. The radiator and all lines to the heaters or
to the engine contain hot coolant.

Any contact with hot coolant or with steam can cause
severe burns. Allow cooling system components to
cool before the cooling system is drained.

te protective guard. Follow the established

Rollover Protective Structure
(ROPS), Falling Object Protective
Structure (FOPS) or Tip Over
Protection Structure (TOPS)

The ROPS/FOPS Structure (if equipped) on your
machine is specifically designed, tested and certified
for that machine. Excavators are not equipped
with ROPS structures. Any alteration or any
modification to the ROPS/FOPS Structure could
weaken the structure. This places the operator
into an unprotected environment. Modifications or
attachments that cause the machine to exceed the
weight that is stamped on the certification plate also
place the operator into an unprotected environment.
Excessive weight may inhibit the brake performance,
the steering performance and the ROPS. The
protection that is offered by the ROPS/FOPS
Structure will be impaired if the ROPS/FOPS
Structure has structural damage. Damage to the
structure can be caused by an overturn, a falling
object, a collision, etc.

Do not mount items (fire extinguishers, first aid
kits, work lights, etc) by welding brackets to the
ROPS/FOPS Structure or by drilling holes in the
ROPS/FOPS Structure. Welding brackets or drilling
holes in the ROPS/FOPS Structures can weaken
the structures. Consult your Caterpillar dealer for
mounting guidelines.

The Tip Over Protection Structure (TOPS) is
another type of guard that is used on mini hydraulic
excavators. This structure protects the operator in
the event of a tipover. The same guidelines for the
inspection, the maintenance and the modification of
the ROPS/FOPS Structure are required for the Tip
Over Protection Structure.

Other Guards (If Equipped)

Protection from flying objects and/or falling objects is
required for special applications. Logging applications
and demolition applications are two examples that
require special protection.

A front guard needs to be installed when a work
tool that creates flying objects is used. Mesh
front guards that are approved by Caterpillar or
polycarbonate front guards that are approved by
Caterpillar are available for machines with a cab or
an open canopy. On machines that are equipped with
cabs, the windshield should also be closed. Safety
glasses are recommended when flying hazards exist
for machines with cabs and machines with open
canopies.

If the work material extends above the cab, top
guards and front guards should be used. Typical
examples of this type of application are listed below:

Rated loads will vary with different attachments.
Contact your Caterpillar dealer regarding the rated
load for specific attachments.

The rated operating load for skid steer loaders that
are equipped with rubber tires is defined by the SAE
standard “J818” (May 1987) and by the ISO 5998
(1986) as 50% of the full static tipping load on a
hard, smooth, level surface. The rated operating
load for machines that are equipped with steel tracks
is defined by the SAE standard “J818” (May 1987)
and by the ISO 5998 (1986) as 35% of the full static
tipping load on a soft, less smooth or level surface.

Rated Loads for Forks

Failure to comply to the rated load can cause pos­sible personal injury or property damage. Review
the rated load of a particular work tool before per­forming any operation. Make a djustments to the
rated load as necessary for non-standard config­urations.

Note: Rated loads should be used as a guide.

Attachments, uneven ground conditions, soft ground
conditions, or poor ground conditions have effects on
rated loads. The operator is responsible for being
aware of these effects.

The rated operating load is defined by SAE J1197
FEB 91 and EN474. The rated operating load is the
least amount of weight of the following conditions:

35% of the full static tipping load on a soft, less

•

smooth or level surface or 50% of the full static
tipping load on a hard, smooth, level surface

100% of the lifting capacity

•

Failure to comply to the rated load can cause pos­sible personal injury or property damage. Review
the rated load of a particular work tool before per­forming any operation. Make a djustments to the
rated load as necessary for non-standard config­urations.

Note: Ratedloadsshouldbeusedasaguide.

Attachments, uneven ground conditions, soft ground
conditions, or poor ground conditions have effects on
rated loads. The operator is responsible for being
aware of these effects.

The maximum placement height (ground line to the
chain hook) is given for the highest position of the
material handling arm. The maximum reach (front
of the machine to the chain hook) is the maximum
horizontal reach of the material handling arm.

The rated operating capacity is the least amount of
weight of the following conditions:

35% of the full static tipping load on a soft, less

Basic Operation

MSS may be programmed to read a standard
Caterpillar key or an electronic key. The electronic
key contains an electronic chip within the plastic
housing for the key. Each key emits a unique
signal to the MSS. The keys can be identified by a
gray housing or a yellow housing. MSS can have
programmed settings to require an electronic key or
a standard Caterpillar key for starting during certain
periods of time.

When the key start switch of the machine is turned
to the ON position, the ECM will read the unique ID
that is stored in the electronic key. The ECM will
then compare this ID to the list of authorized keys.
The following table tells the operator the status for
starting the machine. The status light is located near
the key start switch.

is a 30 second interval for restarting the machine.
This 30 second interval is counted from the time of
turning the key to the OFF position.

Note: Know your machine’s settings because the use
of an electronic key is no guarantee that the machine

An expiration date can be set for each electronic key
that is contained in the list of keys for the machine.
The key will no longer start the machine when the

It is important to prepare the machine for operation
in temperatures that are below 0 °C (32 °F). It
is also important to follow the appropriate warm
up procedures when the machine is operated in
temperatures that are below 0 °C (32 °F).

Machine preparation for cold weather includes
using the correct hydraulic system oil. The factory
fills the hydraulic system with 10W hydraulic oil
which has a minimum operating temperature of

−20 °C (−4 °F). If the machine will be operated at
temperatures below −20 °C (−4 °F), the 10W oil
must be replaced with 0W30 hydraulic oil in order to
provide the proper oil viscosity. Refer to Operation
and Maintenance Manual, “Lubricant Viscosities

Supplemental heat is recommended for cold-soaked starts below the minimum ambient temperature. Supplemental heat may be required
for cold-soaked starts that are above the minimum temperature that is stated, de pending on the parasitic load and other factors.
Cold-soaked starts oc cur when the engine has not been operated for a period of time. This allows the oil to become more viscous
due to cooler ambient temperatures.

API CF oils are not recommended for Caterpillar 3500 Series and smaller Direct Injection (DI) diesel engines. API CF-4 oils are not
recommended for Caterpillar diesel engines.

API CI-4, API CI-4 PLUS, and API CH-4 oils are acceptable if the requirements of Caterpillar’s ECF-1 (Engine Crankcase Fluid specification

- 1) are met. API CI-4, API CI-4 PLUS, and API CH-4 oils that have not met the requirements of Caterpillar’s ECF-1 specification may cause
reduced engine life.

(5)

API CG-4 oils are acceptable for use in all Caterpillar machine diesel engines. When API CG-4 oils are used, the oil change interval
should not ex ceed 250 hours. API CG-4 oils that also meet API CI-4, API CI-4 PLUS, or API CH-4 must also meet the requirements
of the Caterpillar ECF-1 specification.

Welding on Machines and
Engines with Electronic
Controls

SMCS Code: 1000; 7000

Proper welding procedures are necessary in order to
avoid damage to the electronic controls and to the
bearings. When possible, remove the component
that must be welded from the machine or the engine
and then weld the component. If you must weld near
an electronic control on the machine or the engine,
temporarily remove the electronic control in order to
prevent heat related damage. The following steps
should be followed in order to weld on a machine or
an engine with electronic controls.

1. Turn off the engine. Place the engine start switch
in the OFF position.

2. If equipped, turn the battery disconnect switch to
the OFF position. If there is no battery disconnect
switch, remove the negative battery cable at the
battery.

NOTICE
Do NOT use electrical components (ECM or ECM sen­sors) or electronic component grounding points for
grounding the welder.

3. Clamp the ground cable from the welder to the

component that will be welded. Place the clamp
ascloseaspossibletotheweld.Makesurethat
the electrical path from the ground cable to the
component does not go through any bearing. Use
this procedure in order to reduce the possibility of
damage to the following components:

Bearings of the drive train

•

Hydraulic components

•

Electrical components

•

Other components of the machine

•

4. Protect any wiring harnesses from the debris

which is created from welding. Protect any wiring
harnesses from the splatter which is created from
welding.

5. Use standard welding procedures in order to weld

the materials together.
