loosened.
18. Keep the tractor securely supported while
changing the wheels or adjusting the tire tread
width. Make sure to tighten the wheel bolts to the
specified tightening torque.
19. Avoid working under any hydraulically supported
devices. Such devices can leak, suddenly settle
down, or be accidentally lowered. If working
beneath the tractor or an implement is
unavoidable, ensure to use a stand or lift
apparatus with the capacity of more than 3 tons.
20. High pressure hydraulic fluid when released can
penetrate human skin, possibly leading to serious
personal injury. Before disconnecting any
hydraulic line, fully release the internal pressure.
Before exerting a pressure to the hydraulic
system, ensure that all connections are tight and
all the lines, pipes and hoses are free from
fractures/fissures or any other damage.
21. Search for leaks with a piece of cardboard.
Protect hands and body from high pressure
fluids.

Any fluid injected into the skin must be surgically
removed within a few hours or gangrene may

service as required.
24. Keep all bolts and nuts tightened, make sure the
tractor and the attachment is in safe working
condition.
25. Avoid changing the engine governor settings or
overspeed the engine. Excessive engine speeds
are dangerous.
26. Observe proper waste disposal laws and
regulations. Prior to disposal, determine the
proper method to dispose of waste from your
local Environmental Protection Agency.
Recycling centers are established to properly
dispose of materials in an environmentally safe
fashion.

Agency regulations when disposing of oil, fuel,
coolant, brake fluids, filters, batteries, tires and

bearings or the engine can be damaged. The use
of water will result in shortened life and reduce
serviceability.
