MAINTENANCE PRECAUTIONS
· Be sure end of grease gun and zerks are clean before using. Debris injected into
bearings, etc. with grease will cause immediate damage.
· DO NOT grease greaseless bearings. They can be identified by blackish/grey
color. DO NOT use a power grease gun to lubricate bearings. These require very
small and exact amounts of lubrication. Refer to the detailed maintenance section for
specific lubrication instructions. DO NOT over-grease bearings.
· Polycarbonate windows should be washed with mild soap or detergent and luke
warm water, using a soft clean sponge or soft cloth. DO NOT use abrasive or alkaline
cleaners or metal scrapers on Polycarbonate windows!
· Be alert to maintenance indicators such as the in-tank filter pressure gauge, hydraulic
reservoir sight gauge, etc. Take the required action to correct any problems immediately.
·Release of energy from pressurized systems may cause inadvertent actuation of
cylinders, or sudden release of compressed springs. Before disconnecting any hoses
relieve pressure by shutting tractor off, setting cutter on ground and actuating lift valve
handles.
DO NOT use hands to check for suspected leaks in hydraulic hoses!
Hydraulic fluid escaping under pressure can have sufficient force to
penetrate skin and cause serious injury. If fluid is injected into skin, it
mustbe surgically removed within a few hours or gangrene may result.
Use a small piece of wood or cardboard, not hands, to search for pin
hose leaks. Be sure all pressure is relieved whenever disconnecting
lines. Be sure all connections are tight and hoses and lines are not
damaged before applying pressure.
BREAK IN PERIOD
In addition to following the break in instructions for your particular tractor, the in-tank
hydraulic fluid filter should be replaced after the first 50 hours of service. Thereafter the
filter should be replaced every 500 hours, or yearly, which ever comes first.
Re-torque wheel lugs after first five hours of operation and periodically thereafter.
See torque specifications listed in the tractor’s service manual for your particular model.
Wheel lugs must always be re-torqued whenever a wheel is removed and
reinstalled.
