SAFETY
169561 3Revision C
GENERAL SAFETY
CAUTION
The following are general farm safety
precautions that should be part of your
operating procedure for all types of machinery.
Protect yourself.
When assembling, operating and servicing
machinery, wear all the protective clothing
and personal safety devices that COULD be
necessary for the job at hand. Don't take
chances.
You may need:
oa hard hat.
oprotective shoes with slip resistant
soles.
oprotective glasses or goggles.
oheavy gloves.
owet weather gear.
orespirator or filter mask.
ohearing protection. Be aware that
prolonged exposure to loud noise can
cause impairment or loss of hearing.
Wearing a suitable hearing protective
device such as ear muffs (A) or ear
plugs (B) protects against objectionable
or loud noises.
Provide a first-aid kit for use in case of
emergencies.
Keep a fire extinguisher on the machine. Be
sure the extinguisher is properly maintained
and be familiar with its proper use.
Keep young children away from machinery at
all times.
Be aware that accidents often happen when
the operator is tired or in a hurry to get
finished. Take the time to consider the safest
way. Never ignore warning signs of fatigue.
Wear close-fitting clothing and cover long
hair. Never wear dangling
items such as scarves or
bracelets.
Keep hands, feet, clothing
and hair away from moving
parts. Never attempt to clear
obstructions or objects from
a machine while the engine
is running.
Keep all shields in place. Never alter or
remove safety equipment. Make sure driveline
guards can rotate independently of the shaft
and can telescope freely.
Use only service and repair parts made or
approved by the equipment manufacturer.
Substituted parts may not meet strength,
design, or safety requirements.
Do NOT modify the machine. Unauthorized
modifications may impair the function and/or
safety and affect machine life.
(continued next page)
A B

SAFETY
169561 4Revision C
Stop engine and remove key from ignition
before leaving Operator’s seat for any
reason. A child or even a pet could engage
an idling machine.
Keep the area used for servicing machinery
clean and dry. Wet or oily floors are
slippery. Wet spots can be dangerous when
working with electrical equipment. Be sure
all electrical outlets and tools are properly
grounded.
Use adequate light for the job at hand.
Keep machinery clean. Do NOT allow oil or
grease to accumulate on service platforms,
ladders or controls. Clean machines before
storage.
Never use gasoline, naphtha or any volatile
material for cleaning purposes. These
materials may be toxic and/or flammable.
When storing machinery, cover sharp or
extending components to prevent injury
from accidental contact.

GENERAL
169561 5Revision C
RECOMMENDED TORQUES
A. GENERAL
Tighten all bolts to the torques specified in
chart unless otherwise noted throughout
this manual.
Check tightness of bolts periodically, using
bolt torque chart as a guide.
Replace hardware with the same strength
bolt.
Torque figures are valid for non-greased or
non-oiled threads and heads unless
otherwise specified. Do not grease or oil
bolts or capscrews unless specified in this
manual.
When using locking elements, increase
torque values by 5%.

** Always default to the torque value for evaluation of adequate
torque
*** O-ring face seal type end not defined for this tube size.
a. Check components to ensure that the sealing
surfaces and fitting threads are free of burrs,
nicks, and scratches, or any foreign material.
b. Apply lubricant (typically Petroleum Jelly) to
O-ring and threads. If O-ring is not already
installed, install O-ring.
c. Align the tube or hose assembly. Ensure that
flat face of the mating flange comes in full
contact with O-ring.
d. Thread tube or hose nut until hand-tight. The
nut should turn freely until it is bottomed out.
Torque fitting further to the specified number of
F.F.F.T (“Flats From Finger Tight”), or to a given
torque value in the table shown in the opposite
column.
NOTE
If available, always hold the hex on the
fitting body to prevent unwanted rotation
of fitting body and hose when tightening
the fitting nut.
e. When assembling unions or two hoses together,
three wrenches will be required.
