SAFETY
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. Doctors unfamiliar with this type of injury should reference a
knowledgeable medical source.
SERVICE SPREADER SAFELY
To help prevent personal injury caused by unexpected movement, be sure
to service spreader on level surface.
If spreader is connected to tractor, disengage PTO, engage parking brake
and/or place transmission in “PARK,” shut off engine and remove key.
If spreader is detached from tractor, block wheels and use safety stands to
prevent movement.
Replace all shields after lubricating or servicing.
REDUCE SPEED WHEN TOWING LOADS
Braking to stop towed loads from transport speeds can cause the towed
load to swerve and upset. Reduce speed if towed load weighs more than
the tractor and is not equipped with brakes.
Follow recommended speed-weight ratio guidelines:
•Maximum speed is 20 mph (32 km/h) when towing loads equal to or
less than the tractor.
• Reduce speed to 10 mph (16 km/h) when towing loads more than equal
and up to double the tractor weight.
• Do not tow loads exceeding double the tractor weight.
• Use additional caution when towing loads under adverse surface
conditions, when turning, and on inclines
