SAFETY INSTRUCTIONS (CONT’D)
Fire Prevention
The machines and some attachments have components
that are at high temperatures under normal operating
conditions. The primary source of high temperatures is
the engine and exhaust system. The electrical system, if
damaged or incorrectly maintained, can be a so urce of
arcs or sparks.
Flammable debris (leaves, straw, etc.) must be removed
regularly. If flammable debris is allowed to accumulate, it
can cause a fire hazard. Clean often to av oid this
accumulation. Flammable debris in the engine
compartment is a potential fire hazard.
• Do not use the machine where exhaust, arcs, sparks
or hot components can contact flammable material,
explosive dust or gases.
• The operator cab, engine compartment and engine
cooling system must be inspected every day and
cleaned if necessary to prevent fire hazards and
overheating.
• Check all electrical wiring and connections for
damage. Keep the battery terminals clean and tight.
Repair or replace any damaged part.
• Check fuel and hydraulic tubes, hoses and fittings for
damage and leakage. Never use open flame or bare
skin to check for leaks. Tighten or replace any parts
that show leakage. Always clean fluid spills. Do no t
use gasoline or diesel fuel for cleaning parts. Use
commercial nonflammable solvents.
• Do not use ether or starting fluids on any engine that
has glow plugs. These starting aids can cause
explosion and injure you or bystanders.
• Always clean the machine and disconnect the battery
before welding. Cover rubber hoses, battery and all
other flammable parts. Keep a fire extinguisher near
the machine when welding. Have good ventilation
when grinding or welding painted parts. Wear dust
mask when grinding painted parts. Toxic dust or gas
can be produced.
• Stop the engine and let it cool before adding fuel. No
smoking!
• Use the procedure in the Operation & Maintenance
Manual for connecting the battery and for jump
starting.
Figure 1
• Know where fire extinguishers and first aid kits are
located and how to use them. Fire extinguishers are
available from your Ingersoll-Rand dealer [Figure 1].
NOTE: The engine in this machine is factory
equipped with a spark arrestor exhaust
system. It is a violation of California Public
Resource Code Section 4442 to use or
operate this engine on or near any forest-
covered, brush-covered or grass-covered
land unless the exhaust system is equipped
with a spark arrestor meeting any applicable
spark arrestor standards. All spark arrestors
