FOLLOW SAFE PROCEDURE

Unsafe work practices are dangerous. Understand
service procedure before doing work; Do not attempt
shortcuts.

WEAR PROTECTIVE CLOTHING

Wear close fitting clothing and safety equipment
appropriate to the job.

WARN OTHERS OF SERVICE WORK

Unexpected machine movement can cause serious
injury.
Before performing any work on the excavator, attach a

Do Not Operate

tag on the right side control lever.

USE HANDHOLDS AND STEPS

Falling is one of the major causes of personal injury.
When you get on and off the machine, always maintain
a three point contact with the steps and handrails and
face the machine. Do not use any controls as
handholds.
Never jump on or off the machine. Never mount or
dismount a moving machine.
Be careful of slippery conditions on platforms, steps,
and handrails when leaving the machine.

SECTION 1 GENERAL

GROUP 1 SAFETY

1 - 1

KEEP RIDERS OFF EXCAVATOR

Only allow the operator on the excavator. Keep riders
off.

Riders on excavator are subject to injury such as being
struck by foreign objects and being thrown off the
excavator. Riders also obstruct the operator's view
resulting in the excavator being operated in an unsafe
manner.

MOVE AND OPERATE MACHINE SAFELY

Bystanders can be run over. Know the location of
bystanders before moving, swinging, or operating the
machine.

Always keep the travel alarm in working condition. It
warns people when the excavator starts to move.

Use a signal person when moving, swinging, or
operating the machine in congested areas. Coordinate
hand signals before starting the excavator.

OPERATE ONLY FORM OPERATOR'S SEAT

Avoid possible injury machine damage. Do not start
engine by shorting across starter terminals.

NEVER start engine while standing on ground. Start
engine only from operator's seat.

PARK MACHINE SAFELY

Before working on the machine:

Park machine on a level surface.
Lower bucket to the ground.
Turn auto idle switch off.
Run engine at 1/2 speed without load for 2 minutes.
Turn key switch to OFF to stop engine. Remove key

from switch.

Move pilot control shutoff lever to locked position.
Allow engine to cool.

1 - 3

SUPPORT MACHINE PROPERLY

Always lower the attachment or implement to the
ground before you work on the machine. If you must
work on a lifted machine or attachment, securely
support the machine or attachment.

Do not support the machine on cinder blocks, hollow
tiles, or props that may crumble under continuous load.
Do not work under a machine that is supported solely by
a jack. Follow recommended procedures in this manual.

SERVICE COOLING SYSTEM SAFELY

Explosive release of fluids from pressurized cooling
system can cause serious burns.

Shut off engine. Only remove filler cap when cool
enough to touch with bare hands.

HANDLE FLUIDS SAFELY-AVOID FIRES

Handle fuel with care; It is highly flammable. Do not
refuel the machine while smoking or when near open
flame or sparks. Always stop engine before refueling
machine.
Fill fuel tank outdoors.

Store flammable fluids away from fire hazards. Do not
incinerate or puncture pressurized containers.

Make sure machine is clean of trash, grease, and
debris.

Do not store oily rags; They can ignite and burn
spontaneously.

1 - 4

BEWARE OF EXHAUST FUMES

Prevent asphyxiation. Engine exhaust fumes can
cause sickness or death.

If you must operate in a building, be positive there is
adequate ventilation. Either use an exhaust pipe
extension to remove the exhaust fumes or open doors
and windows to bring enough outside air into the area.

REMOVE PAINT BEFORE WELDING OR HEATING

Avoid potentially toxic fumes and dust.

Hazardous fumes can be generated when paint is
heated by welding, soldering, or using a torch.

Do all work outside or in a well ventilated area.
Dispose of paint and solvent properly.

Remove paint before welding or heating:

If you sand or grind paint, avoid breathing the dust.

Wear an approved respirator.

If you use solvent or paint stripper, remove stripper

with soap and water before welding. Remove
solvent or paint stripper containers and other
flammable material from area. Allow fumes to
disperse at least 15 minutes before welding or
heating.

ILLUMINATE WORK AREA SAFELY

Illuminate your work area adequately but safely. Use a
portable safety light for working inside or under the
machine. Make sure the bulb is enclosed by a wire
cage. The hot filament of an accidentally broken bulb
can ignite spilled fuel or oil.

1 - 5

SERVICE MACHINE SAFELY

Tie long hair behind your head. Do not wear a necktie,
scarf, loose clothing or necklace when you work near
machine tools or moving parts. If these items were to
get caught, severe injury could result.

Remove rings and other jewelry to prevent electrical
shorts and entanglement in moving parts.

STAY CLEAR OF MOVING PARTS

Entanglements in moving parts can cause serious
injury.

To prevent accidents, use care when working around
rotating parts.

AVOID HIGH PRESSURE FLUIDS

Escaping fluid under pressure can penetrate the skin
causing serious injury.

Avoid the hazard by relieving pressure before
disconnecting hydraulic or other lines. Tighten all
connections before applying pressure.

Search for leaks with a piece of cardboard. Protect
hands and body from high pressure fluids.

If an accident occurs, see a doctor immediately. Any
fluid injected into the skin must be surgically removed
within a few hours or gangrene may result.

1 - 6

AVOID HEATING NEAR PRESSURIZED FLUID
LINES

Flammable spray can be generated by heating near
pressurized fluid lines, resulting in severe burns to
yourself and bystanders. Do not heat by welding,
soldering, or using a torch near pressurized fluid lines or
other flammable materials.

Pressurized lines can be accidentally cut when heat
goes beyond the immediate flame area. Install fire
resisting guards to protect hoses or other materials.

PREVENT BATTERY EXPLOSIONS

Keep sparks, lighted matches, and flame away from the
top of battery. Battery gas can explode.

Never check battery charge by placing a metal object
across the posts. Use a volt-meter or hydrometer.

Do not charge a frozen battery; It may explode. Warm
battery to 16

C(60 F).

PREVENT ACID BURNS

Sulfuric acid in battery electrolyte is poisonous. It is
strong enough to burn skin, eat holes in clothing, and
cause blindness if splashed into eyes.

Avoid the hazard by:

1. Filling batteries in a well-ventilated area.
2. Wearing eye protection and rubber gloves.
3. Avoiding breathing fumes when electrolyte is added.
4. Avoiding spilling of dripping electrolyte.
5. Use proper jump start procedure.

If you spill acid on yourself:

1. Flush your skin with water.
2. Apply baking soda or lime to help neutralize the

acid.

3. Flush your eyes with water for 10-15 minutes. Get

medical attention immediately.

If acid is swallowed:

1. Drink large amounts of water or milk.
2. Then drink milk of magnesia, beaten eggs, or

vegetable oil.

3. Get medical attention immediately.

1 - 7

USE TOOLS PROPERLY

Use tools appropriate to the work. Makeshift tools,
parts, and procedures can create safety hazards.

Use power tools only to loosen threaded tools and
fasteners.

For loosening and tightening hardware, use the correct
size tools. DO NOT use U.S. measurement tools on
metric fasteners. Avoid bodily injury caused by slipping
wrenches.

Use only recommended replacement parts.(See Parts
catalogue.)

DISPOSE OF FLUIDS PROPERLY

Improperly disposing of fluids can harm the environment
and ecology. Before draining any fluids, find out the
proper way to dispose of waste from your local
environmental agency.

Use proper containers when draining fluids. Do not use
food or beverage containers that may mislead someone
into drinking from them.

DO NOT pour oil into the ground, down a drain, or into a
stream, pond, or lake. Observe relevant environmental
protection regulations when disposing of oil, fuel,
coolant, brake fluid, filters, batteries, and other harmful
waste.

REPLACE SAFETY SIGNS

Replace missing or damaged safety signs. See the
machine operator's manual for correct safety sign
placement.

LIVE WITH SAFETY

Before returning machine to customer, make sure
machine is functioning properly, especially the safety
systems. Install all guards and shields.
