• Use the appropriate tools in proper size. If an inappro-
priate tool is used, it can be slipped which can dam-
age parts or injure you.
• Do not confuse units (mm, inch, etc.).
• Use the air impact wrench only when unscrewing the
bolts or nuts. Such wrench should not be used when
assembly precisely machined parts which its tighten-
ing torque should be strictly observed. It can cause
malfunction.
• Be careful of a socket popped out due to the turning
force when using the air impact wrench. Especially, be
extra cautious when working on connection or socket
with joint.
• When lifting the combine harvester with a hydraulic
jack or a hoist, fix it firmly and install the auxiliary sup-
port. Never work under the combine harvester if the
support and the hydraulic jack (hoist) are not installed.
• When using a hydraulic jack or a hoist, do not use it
over the limit of the equipment and the conveying belt.
• Make sure that the hydraulic lock operates properly
before using the hydraulic jack. Improper use of lock
can cause a serious accident.
• Check the buttons and operating direction of the hoist
before using it. Improper operation can cause a seri-
ous accident.
• Do not use wooden blocks or bricks as support under
the combine harvester. As the combine harvester's
weight is continuously applied to them, they can be
broken or collapsed.
• Do not use pressurized air to blow out hazardous ma-
terials, such as clutch dust, with compressed air. Inhal-
ing such hazardous materials can damage your health.
