2. Safety tips
2.2.1 Ventilating system
When working on the tractor, wear safety gloves, safety shoes, ear plugs, safety goggles, safety helmet, working clothes, etc. appropriate for your working environment. Never wear loose fitting clothing or a tie which can be caught by a rotating part. According to the statistics, most accidents that occurred with rotating parts are due to this inappropriate manner of wearing clothes.
The service should be performed in well-ventilated area. If the engine should be started in an enclosed place, the exhaust gas vent pipe should be installed.
WARNING • California Proposition 65 Warning Inhaling exhaust gas can cause cancer or damage the generative function leading to infertility.
2.2.3 Illumination The work place should be well illuminated. If working in a dark place or under the tractor, use the work lamp. The work lamp should be covered by the safety cover. Light bulbs can cause fire if exposed to fuel leaks.
ELECTRIC & CALIBRATION
The work should be done in a wide, level and safe place to prevent slip and fall accident.

2.5 Cautions when handling the battery
SAFETY FIRST
DX7510/9010/100
Always disconnect the negative battery cable first and reconnect it last to avoid sparks from an accidental short circuit. You could be injured or fire may break out.
•
The hydraulic fluid leaks from high pressure hoses or pipes can penetrate your skin.
Keep sparks and flames (match, lighter) away from the battery. The battery can explode due to the battery fluid.
•
Never connect the battery’s negative and positive cables with metal for test. Use only tester when checking the battery voltage.
Before connecting a high pressure hose or pipe, stop the engine and depressurize it by valve.
•
Check the bolts for tightness before starting the engine after servicing the hydraulic system.
•
Use a cardboard or plank when checking leakage.

2.7 Use of appropriate tools and equipment •
Use the appropriate tools and proper size. If an inappropriate tool is used, it can slip which can damage 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 tightening torque should be strictly observed. It can cause malfunctions.

2.8 Handling of hazardous materials •
Do not blow out hazardous materials, such as clutch dust, with compressed air. Inhaling such hazardous materials can damage your health.
Remark No genuine DAEDONG part contains asbestos.
•
These materials should be rinsed or wiped away after spraying with oil.
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.
T46W022A
•
When lifting the tractor with a hydraulic jack or a hoist, fix it firmly and install the auxiliary support. Never work under the tractor 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 serious accident.
•
Do not use wooden blocks or bricks as support under the tractor. As the tractor’s weight is continuously applied to them, they can be broken or collapsed.

•
Do not open the radiator cap when the radiator is hot. Hot coolant or steam can be surged leading to a serious scald.
Do not set a hand or a foot into the tractor’s rotating blade or PTO shaft.
•
Do not wear loose clothing.
Check the surface temperature of the container before draining the engine oil, transmission fluid, coolant, etc. If it is hot, let it cool down before draining it. There is danger of burning.
Be careful not to get caught by the rotating engine cooling fan.
•
Perform any service on the engine parts (muffler, exhaust manifold, turbocharger, etc.) only when they are not hot.
