FAILURE IN OPERATION

•In the event of poor performance or machine failure,

stop the machine immediately and report the matter.

Take measures to prevent further use until the

malfunction is corrected (Place a DO NOT OPERATE

tag on the control panel, remove the key, turn off all

power sources, etc.) Before working on any hydraulic

or electrical circuits, refer to the maintenance sections

in this manual.

•Support or lower all attachments to the ground before

leaving or servicing the vehicle.

MACHINE OPERATION

•Check all controls in a clear area and make sure the

machine is operating correctly.

•DO NOT let other persons ride on the machine. Other

persons can fall or will cause an accident.

•Dust, fog, smoke, snow, etc., may decrease your vision

the work area.

•Contact with high voltage power lines, underground

cables, etc., can cause serious injury or death from

electrocution.

•Before you drive or operate in an area with high

voltage lines or cables, contact your utility companies

or one of the Digging Hot Line numbers. You MUST

HAVE THE POWER DISCONNECTED OR KEEP A

SAFE WORKING DISTANCE from the lines or

cables. You must know the safe working distance from

the high voltage power equipment and must know any

federal, state/provincial or local safety codes or

regulations that apply to the job site.

underground objects can cause injury or death. Learn

the location of underground hazards before you

operate your machine in a new area.

•If this machine turns over, you can be injured or killed.

You must make a judgment if weather, road or earth

conditions will permit safe operation on a hill, ramp or

rough ground.

•Stay away from hazardous areas such as ditches,

overhangs, etc. Walk around the work area before you

start and look for hazards.

•Be alert and always know the locations of all workers in

your area. Keep all other persons completely away

from your machine. Injury or death can result if you do

not follow these instructions.

•If your view of the work area is not clear, always have

a signal person direct your movement. Know and

understand each signal from the signal person before

you start.

•Operate the machine controls from the operators seat

only.

•DO NOT operate this machine while under the

influence of alcohol or drugs.

• NEVER allow anyone in the trench while digging.

• NEVER allow anyone to stand in the vicinity of the

trench while operating the trencher or backfill blade.

Stop the trencher and ground drive if anyone comes

close to the trencher or machine.

PARKING THE MACHINE

•When you park the machine, select level ground

whenever possible. If you must park on a slope or

incline, position the machine at right angles to the

slope.

see your dealer.

•Unauthorized modifications to this machine can cause

injury or death. Do not make unauthorized

modifications to this machine. Always see your dealer

before you weld, cut or drill holes in your machine.

•When you service this machine, always wear face or

eye protection, safety shoes and other protective items

as required.

•If you must service this machine with the engine

running, have another person help you. Follow the

instructions in this manual or the Service Manual. Do

not leave the operator’s seat with the engine

running.

•Metal chips or debris can cause eye injury. Always wear

eye or face protection especially when you use a

hammer on this machine. Use a hammer with a soft

face, such as brass, to drive hardened pins.

•When you replace parts on your machine, always use

Astec parts. See your dealer.

•If you must service the machine with an attachment

raised, always block up the attachment.

•To prevent accidental movement of the machine,

always block the tires before you service the machine.

BURN PREVENTION

•Battery acid causes severe burns. Batteries contain

sulfuric acid. Avoid contact with skin, eyes, or clothing.

Antidote - EXTERNAL: Flush with water. INTERNAL:

Drink large quantities of water or milk. Follow with milk

of magnesia, beaten egg or vegetable oil. Call a doctor

immediately. EYES: Flush with water for 15 minutes

and get prompt medical attention.

•When the battery electrolyte is frozen, the battery can

explode if, (1) you try to charge the battery, or (2) you

try to jump start and run the engine. To prevent the

battery electrolyte from freezing, try to keep the

battery at full charge. If you do not follow these

instructions, you or others in the area can be injured.

PRESSURIZED HYDRAULIC

FLUID AND GREASE

•Hydraulic fluid or grease injected into your skin can

cause severe injury or death. Keep your hands and

body away from any pressurized leak. If fluid is

injected into your skin, get medical attention

immediately and have the fluid removed.

HAZARDOUS CHEMICALS

•If you are exposed to or come in contact with

hazardous chemicals you can be seriously injured. The

fluids, lubricants, paints, adhesives, coolants, etc.,

used with your machine can be hazardous.

•Material Safety Data Sheets (MSDS) provide

information about the chemical substances within a

product, safe handling procedures, first aid measures

and procedures to be taken when the product is

accidentally spilled or released. MSDS are available

from your dealer.

WARNING:

Battery acid may cause burns.

Avoid contact.

WARNING:

Fluid under pressure can pierce

skin and cause injury or death. Stay away.

WARNING:

Improper handling or use of

chemicals may result in illness, injury, or

equipment damage. Follow instructions on

labels and in material safety data sheets

(MSDS).

SAFETY

9 AU103168 C7B

•Before you service your machine, check the MSDS for

each fluid, lubricant, etc., used in this machine. This

information indicates what the risks are and how to

service the machine safely. Follow this information

when servicing the machine.

•Before you service this machine and before you

dispose of the old fluids and lubricants, always

remember the environment. DO NOT put oil or fluids

into the ground or into containers that can leak.

•Check with your local environmental or recycling center

or your dealer for correct disposal information.

FIRE OR EXPLOSION

PREVENTION

•Engine fuel can cause an explosion or fire. Do not fill

the fuel tank with the engine running, if you are near

an open fire, or if you are welding, smoking, etc.

•Use nonflammable cleaning solvent to clean parts.

•Sparks or flame can cause the hydrogen gas in a

battery to explode. To prevent an explosion, do the

following:

1. When disconnecting the battery cables, disconnect

the negative (-) cable first; when connecting the

battery cables, connect the negative (-) cable last.

2. When connecting jumper cables to start the engine,

use the procedure shown in this manual. See Booster

Battery Connections in this manual.

3. Do not short circuit the battery posts with metal

items.

4. Do not weld, grind, or smoke near a battery.

•Sparks from the electrical system or engine exhaust

can cause an explosion and fire. Before you operate

this machine in an area with flammable dust or vapors,

use good ventilation to remove the flammable dust or

vapors before you start.

•Remove all trash or debris from the machine. Make

sure that oily rags or other flammable materials are not

stored on the machine.

•A fire can cause injury or death. Always have a fire

extinguisher near by or on the machine. Make sure the

fire extinguisher is serviced according to the

manufacturers instructions.

•Check for fuel, oil, and hydraulic fluid leaks. Replace

worn or damaged hoses or lines. After repairs are

made, clean the machine before you operate.
