POWER UNIT / UH070-3

1. Before Starting Engine:

 (1) Engine Oil:
 Check the engine oil level by oil gauge.
 Refill engine oil when the oil is below the min. level.
 Recommended engine oil: SAE 10W-30 or equivalent. Capacity: 0.6L

 (2) Hydraulic Oil:
 Refill hydraulic oil when the oil level is below the oil indication window.
 Open the plug on the top of the oil tank,
 pour in hydraulic oil till the oil level reach to the middle of the indication window.
 Recommended hydraulic oil: ISO VG32 or equivalent.  Capacity: 4L

 (3) Fuel:
 Refill gasoline into the fuel tank.
 Capacity: 3.6L
 * Wipe out spilled gasoline on machines.

2. Starting Engine:

 (1) Attach power unit and equipment (breakers and etc.) with connection hoses before starting engine.
 DO NOT start engine without connecting to equipment with hoses.
 MAKE SURE control lever indicate to “START” position.

 (2) Start operation

  ①Open the fuel cock.

  ②Turn the switch to “ON”

  ③Turn the speed control lever from low speed (L) toward to high speed (H) and stop at 1/3 closer to (H) position.

  ④Close the choke lever.
  When to open the choke lever:
  ･When the weather is cold or when the engine is cold, close the choke lever.
  ･When the weather is warm or when starting the engine right after stopping,
   fully or partially open the choke.

  ⑤Pull start rope gradually.
  DO NOT pull the starting rope rapidly.
  After the rope being fully pulled, DO NOT release it from your hand.
  Hold the starting rope till it returns to its original position.

  ⑥After the engine being started, open the choke lever.
  Open the choke lever gradually according to the engine’s condition.
  Eventually, the choke lever should be fully opened.
  ･When the weather is cold, engine might stop if you turn the choke lever too rapidly.

3. Operation:

 (1) Turn the throttle to high speed (H)

 (2) Turn the control lever to the “OPERATE” position.
 (Refer to the drawing on the right)

 (3) Read through all operating manuals of equipment which you intend to use with this power unit.

 (4) When stopping the operation of the equipment (breakers and etc.) ALWAYS turn the engine throttle to the Low Speed (L) side.
 This can save energy and reduce the noise level.

4. Stop:

 (1) Turn the speed control lever to Low Speed (L) side and run the machine for 1 to 2 minutes.

 (2) Turn the switch to “O” Off side.

(3) Turn off the fuel cock.

(4) Detach connection hoses from equipment (breakers and etc.)
 Connect couplers on the hoses together. 

< CAUTION >
 The temperature of the machine goes high while being operated.
 Always wear gloves when operating the equipment (breakers and etc.)

1. DAILY INSPECTIONS

 (1) Check the engine oil level each time before starting the engine.

 (2) Make sure hydraulic oil is above the middle line on the indicator window.
 Refill hydraulic oil if necessary. (Recommended Hydraulic Oil: ISO VG32 or equivalent)

 (3) Clean the element of the air cleaner in the engine.

 (4) Make sure there is no oil leakage from the pump and hoses.
 Tighten up the hose joints and bolts if necessary.

 (5) Start the engine, make it run in low speed (Idling) and make sure there is no abnormal sound and abnormal movement.
 Refill the oil. (Recommended Hydraulic Oil: ISO VG32 or equivalent)

2. PERIODICAL INSPECTIONS

To keep the power unit in a good condition, make sure the following maintenance items are done periodically. 

*The first replacement is 20 hours

 (1) Draw out the hydraulic oil from the drain plug at the bottom of the oil tank.
  ①Changing the hydraulic oil when the color of the hydraulic oil changed or when it smells burning.
 Always replace the same type of hydraulic oil.

 (2) Suction filter should be cleaned by non-lead gasoline.

 (3) Blow away the dust, dirt from oil cooler.

 (4) Inspect the connection hoses which connected to breaker thoroughly.
 Replace a new one if there are scratches, damages which may lead to oil leakage.
