6. EFFICIENT WORKING METHOD 1) THINK-SAFETY FIRST In special situation, wear protective clothing including a safety helmet, safety shoes, gloves, safety glasses and ear protection as required by the job condition. Almost every accident are caused by disregarding the simple and fundamental safety hints.

Be sure to understand thoroughly the operator’s manual before operating the machine.

Fully understand the details and process of the construction before starting the work.

If you find anything dangerous on the job, consult with the job supervisor for preventive measures before operating the machine.

Do not operate when tired, or after drinking. Alcoholic beverages, or any type of drugs.

Check daily according to the operator’s manual. Repair the damaged parts and tighten the loosened bolts.

Check for leakage of engine oil, hydraulic oil, fuel and coolant.

Do not operate the machine if it requires repairs. Operate after complete repair.

When installing and using an optional attachment, read the instruction manual for the attachment and the information related to attachments in this manual.

Do not use attachments that are not authorized by or your distributor. Use of unauthorized attachments could create a safety problem and adversely affect the proper operation and useful life of the machine.

Only trained and authorized personnel can operate and maintain the machine.

Follow all safety rules, precautions and instructions when operating the machine.

When working with another operator or a person on worksite traffic duty, be sure all personnel understand all hand signals that are to be used.

Always use seat belts when operating your machine.

4-11

2) LOADER OPERATION (1) General ① Use the handle and footstep when getting on or off the machine.

Do not jump on or off the machine. ② Sound the horn to warn nearby personnel before operating the machine. ③ Operate carefully to make sure all personnel or obstacles are clear within the working range of the machine.

Place safety guards if necessary. ④ Check the locations of underground gas pipes or water line and secure the safety before operation. ⑤ When the bucket is loaded, avoid sudden swinging or starting. Overloading is dangerous.

Make sure the load does not exceed the permissible level. ⑥ The operation on a slope is dangerous.

Avoid operating the machine on a slope of over 10 degree.

Operate the machine after making ground flat when operation is required on a slope. ⑦ Steering of the machine while traveling on a slope is dangerous.

When an inevitable turning of direction is required, turn on the flat and solid ground. ⑧ Avoid operating on a cliff, or soft ground as there is danger of rolling over.

Take necessary precautions when working after rain, or blasting because the ground may not be firm enough. ⑨ The ride control switch (if fitted) will smooth the ride of the machine during traveling uneven grounds.

(2) Shovel work ※ As the machine loads on the bucket with traveling, tires may start to slip because of heavy load.

Then lift the bucket slightly to reduce load.

Horn Clutch cut-off switch Clam

※ The low speed control switch is used to give more traction force and slow down the loader operation. Use only this switch intermittently such as entering the stockpile. ※ The clutch cut off switch is used to give more power to the loader and speed operation.

H930ST4OP77

① Keep the bucket shovel parallel to the ground. ※ If the bucket is pushed in a non-horizontal position, power may be reduced, and the bucket cannot dig deeply into the heap of soil.

H940C4OP116

② When the bucket is sufficiently deep into the pile, advance the machine with the control lever pulled down. And by placing the control lever in the bucket roll-back position, fill the bucket with soil.

H940C4OP117

③ When it is difficult to dig into the soil, move the bucket control lever forward and backward to move the bucket teeth up and down. ④ If the machine operates with its front tires liftlifted, its driving force will deteriorate and excessive force will be applied to the rear tires. Avoid operating in that posture.

H940C4OP118

4-13

(3) Job layout Set up the work cycle as short as possible. Truck positioning is very important for fast cycles.

Spend a few minutes leveling off the work area, if necessary. Smooth runways for the machine and a level parking area for trucks will speed up the job.

Operating a loader with a full bucket on a hillside can cause the machine to roll over. If possible, avoid turning the machine and always move forward up the hill and back down. Always keep the load low. If you do not follow these instructions, you can be injured or killed.

When you operate the machine, keep the loader bucket as low as possible. This low position gives better balance and permits you to see more clearly. If the bucket is full and you move the machine over ground that is rough or surfaces that can cause the machine to slide, always operate at slow speed. If you do not use this procedure, the machine can go out of control and roll-over.

15. TIRES AND WHEELS 1) TIRE PRESSURE (1) Inappropriate tire pressure is a primary cause for tire damage. Insufficient tire pressure will damage internal carcass of tire. Repeated excessive bending will damage or break the carcass.

Excessive pressure will also cause premature damage of tire.

(2) Recommended tire pressure : Refer to page 5-1.

(When tire is cooled) (3) Continuous operation will produce heat and increase pressure on tire. But such phenomenon was already taken into account when designing a tire. Do not try to remove normally increased air because tires may be crushed or overinflated.

(4) The three major causes for excessive heat and pressure of tire are insufficient pressure, excessive load and overspeed. Avoid excessive load and overspeed in order to keep tires in good shape.

Do not inflate tires using flammable gases or alcohol injector.

This cause explosion or personal injury.

Inflate tires at the pressure level recommended by the manufacturer, and check periodically pressure and wear of tires.

When replacing the inflated tire, do not stand near the tire. ※ Check the tire when the tire is at normal temperature and the machine is not loaded.

Do not use recycled wheel parts.

When removing lockering or inflating tire, use safety cable or chain to ensure safety.

Be sure to bleed air before removing lockering.

Never inflate tires unless the lockering is assembled in its place. ※ Avoid the followings when traveling. ① Rubbing tires against road bank or rack at cargo-unloading spot. ② Tires slippage during working. ③ Abrupt starting of machine. ④ When oil, grease or gasoline smeared on tire, clean those. Otherwise it may cause of permanent deformation.

2) REPLACEMENT OF TIRE Disassembly, reassembly, replacement and repair of tire requires special skills and equipment. Contact a tire repair shop.

The correct torques are shown as below. ·Front / Rear : 79 kgf·m (570 lbf·ft)

3) STORING TIRES AFTER REMOVAL As a basic rule, store the tires in a warehouse which unauthorized persons cannot enter. If the tire are stored outside, always erect a fence around the tires and put up "No Entry" and other warning signs that even young children can understand.

Stand the tire on level ground, and block it securely so that it cannot roll or fall over.

If the tire should fall over, get out of the way quickly. The tires for construction equipment are extremely heavy, so trying to hold the tire may lead to serious injury.
