1. Clearance adjustment of mesh of angel gear in gear-box ( See Figure 10)
① When lateral clearance of mesh of the gear △＜0.05mm,we should put some vulcanized
paper to enlarge the clearance between the gear-box and the traveling box.
② When lateral clearance of mesh of the gear △＞0.3mm,we should reduce the clearance to
0.05-0.10 mm between the bearings and gear Ⅱshaft
2. Clearance adjustment of mesh of the gear in the running case.(See Figure 11)
① When lateral clearance of mesh of the gear △＜0.05mm,we should increase adjustment
pad by 0.2-0.3mm to enlarge the clearance, and change vulcanized paper boardⅡand
adjustmentpad.
Ⅲ. To ensure the axial clearance of the gearⅡis 0.05-0.15mm.
② When lateral clearance of mesh of the gear △＞0.3mm, we should reduce adjustment
padⅠ,meanwhile the axial clearanceof gear Ⅱis 0.05-0.15mm,or increase the adjustment
padⅡ, meanwhileensure the axial clearance of gearⅠis 0.05-0.15mm.
Ⅱ. Debugging Method of Reversing Gears and Cables
When the power tiller’s running backwards is not normal, it is necessary to adjust the
reversing gears and Cables, see Chapter Three for the methods.
Note: 1. Grasp and loosen the reversing handle for 2-3 minutes to confirm the putting into
gear. If it is abnormal, adjust it until it is qualified.
2. When the power tiller is running, loosen the reversing handle, the reversing gears should
return to its original position and no abnormal sound by gears colliding in the gear-box,
otherwise, it may cause damage to the gear.
Ⅲ Debugging Method of Clutch Cables
After some time use, the clutch does not perform well any more due to the weariness of
friction piece and fork of clutch. As for how to adjust cable of the clutch, refer to Chapter
Three for know-how.
Note: 1. Grasp and loosen the clutch handle for 2-3 times to confirm the clutch status. If
abnormal, readjust it.
2. If repeated adjustment can not solve the problem, excess abrasion of fork or friction
piece of the clutch can be confirmed. The machine should be sent to special service centre for
replacing with a new fork of friction piece of the clutch.
3. Dismount the clutch by unspecialized person, which may cause damage to the clutch
and the machine is forbidden.
Ⅳ. Debugging Method of Accelerator Cables
When spinning the throttle switch, acceleration or deceleration performance if the diesel
engine is not good, adjust the throttle switch. Refer to Chapter Three for measures.
Note: 1. Repeatedly spin the throttle switch for 2-3 times and confirm whether the
acceleration or deceleration performance of the diesel engine is ok.
2. Joint of the cable must be firmly connected to the throttle cable.
Ⅴ.Use & Debugging Method of Handle bar Frame
According to your height, farming and other special requirements ,the handle bar connection
can be adjusted up and down, left and right appropriately, measure are interpreted as
following: (see figure 12)
