WORK SAFELY FOLLOW THESE RULES This symbol is
used to call your attention to instructions
concerning your personal safety. Be sure to
observe and follow these instructions. 1. To
prevent injury, do not allow children or
by-standers around the machine while it is being
adjusted and/or serviced.
7. When splitting tractors, or disassembling
machines, be sure to use safety stands and
adequate supports to prevent tipping or rollover.
2. Always use safety stands in conjunction with
hydraulic jacks or hoists. Do not rely on the
jack or hoist to carry the load, they could fail.
8. Use a safety catch on all hoist hooks. Do not
take a chance, the load could slip off of the
hook.

1. Always wear safety glasses when using a hammer,
   chisel or other tools that may cause chips to
   fly.
2. Keep work area organized and clean. Wipe up oil
   or spills of any kind. Keep tools and parts off
   of the floor. Eliminate the possibility of a fall
   which could result in a serious injury.

5. Be sure to reinstall safety devices, guards or
shields after adjusting and/or servicing the
machine.
9. When using an acetylene torch always wear
welding goggles and gloves. Keep a charged fire
extinguisher within reach. Be sure the ace-
tylene and oxygen tanks are separated by a metal
shield and are chained to the cart. Do not weld
or heat areas near fuel tanks or fuel lines and
utilize proper shielding around hydraulic lines.
6. After servicing, be sure all tools, parts, or
servicing equipment are removed from the machine.

• Handle gasoline with care - it is highly
• flammable
• Use approved gasoline container.
• Never remove the fuel tank cap or fill the fuel
  tunk when the engine is run- ning, is hot, or
  indoors. Also, do not smoke when working around
  flammable fuel.

(c)
Wheo refueling, keep the hose and noz- zle of the
funnel and container in con- tact with the metal
of the fuel tank to avoid the possibility of an
electric spark igniting the fuel. Do not overfill
the fuel tank - overflow creates fire hazard.
Wipe up spilled gasoline.
(d)
Replace fuel tank cap securely.
10. Always use a safety bar to block hydraulic
cylinders. Never rely on the machine hydraulic
system to hold when working on loaders, etc. A
hydraulic line or cylinder could fail or some-
one could accidently strike the control levers
causing the loader to fall.
14. Always use a protective fixture when in-
flating tubeless tires that have been repaired or
are loose on the rim. Do not inflate over 30 psi
to seat the tire bead.
15. Use pullers to remove bearings, bushings,
gears, cylinder sleeves, etc. when applicable.
Use hammers, punches and chisels only when abso-
lutely necessary. Then, be sure to wear safety
glasses.
11. Electrical storage batteries give off highly
inflammable hydrogen gas when charging and
continue to do so for some time after receiving a
steady charge. Do not under any
circumstances allow an electric spark or an open
flame near the battery. Always disconnect a
battery cable be- fore working on the electrical
system. f2. Hydraulic fluid escaping under
pressure can have enough force to penetrate the
skin. Hy- draulic fluid may also infect a minor
cut or open- ing in the skin. I f injured by
escaping fluid, see a doctor at once. Serious
infection or reaction can result if medical
treatment is not given immediately.
16. Be careful when using compressed air to dry
parts. Use approved air blow guns, do not exceed
30 psi, wear safety glasses or goggles and use
proper shielding to protect everyone in the work
area.

1. Do not wear rings, wrist watches or loose fitting
   clothing when working on machinery, they could
   catch on moving parts causing serious injury.
   Wear sturdy, rough-soled work shoes. Never adjust
   and/or service a machine in bare feet, sandals or
   sneakers.
2. Excessive or repeated skin contact with sealants
   or solvents may cause skin irritation. In case
   of skin contact, remove sealant or sol- vent
   promptly by washing with soap and water.

Do not attempt to repair or tighten hoses that
are under pressure, when th boom is raised, or
with the tractor engine running. Cycle all hy-
draulic control valves to relieve all pressure
be- fore disconnecting the lines or performing
other work on the hydraulic system. Make sure all
connections are tight and hoses and lines are in
good condition before applying pressure to the
system. To locate a leak under pressure, use a
small piece of cardboard or wood. Never use hands.
IMPORTANT The above is only a partial list of
safe work rules. In addition, always refer to the
Operator's Manual for the specific machine for
additional safe work rules regarding the machine
operation.

STANDARD TORQUE DATA FOR INCH NUTS AND BOLTS
FOOT POUNDS

• Recommended torque for all Standard Unplated Nuts
  and Bolts. provided
• Surface finish is oxide coated, oil quenched or
  bright.
• All thread surfaces are clean and lubricated with
  SAE-30 engine oil or equivalent (See NOTE.)
• Joints are rigid, that is. no gaskets or
  compressibie materials are used.
• When reusing nuts or bolts use minimum torque
  values.

Multiply the standard torque by .65 when
finished jam nuts are used. .7O when Molykote,
white lead or similar mixtures are used as
lubricants. .75 when phosphate coated and oiled
bolts or nuts are used. .85 when cadmium or zinc
