Chapter IV Operation method of the tiller
Before each tiller leaves the factory, it has gone through shakedown test, but the user still should check
all mechanisms of the machine and adjust them before actually using it, so as to let it work better.
i. Routine check
1. Check engine oil
Warning! The engine shall be filled with 0.6L of engine oil. If the level of engine oil is lower than
the normal one when the user is using the engine, the engine will be severely damaged!
Warning! Please use clean and high-quality engine oil for four-stroke engines. Use of dirty oil or
any other type of engine oil will shorten the engine’s service life.
●Put the engine in a horizontal position.
● Screw out the oil dipstick of the engine and clean it by wiping it (See Fig.2)
● Insert the oil dipstick into the oil filler (don’t engage their threaded parts)
● Take out the oil dipstick to check oil level, if it’s within the marked range of the oil dipstick, it is
OK.
● SAE15W 一40 engine oil is a recommended general-purpose lubricant, and is suitable for a
common ambient temperature. (See Table 1)
2. Check lubricant in reduction box

.10.
Figure 2
● Put the tiller on a horizontal ground and screw out the plug (See Fig.4)

ii. Status adjustment of the tiller
1. Adjustment of handle frame
Note: Before adjusting height of handle frame, please put the machine on a flat horizontal ground to
prevent it from accidental falling.
● Loosen the lifting handle and select the hole in an appropriate position, then adjust the handle’s
cross bar to as high as user’s waist, then turn the lifting handle to tighten it (See Fig. 5).
2. Adjustment of tilling depth
● By adjusting height of damping lever, tilling depth can be adjusted. Specifically, adjusting the
lever downward will increase tilling depth, and adjusting it upward will decrease tilling depth. (See Fig.6)
3. Adjustment and use of clutch
Note: Before using the clutch, lower the engine speed.
● By “engage ” and “disengage ”of the clutch, the user can
control output of engine’s power.
● When the user holds tight the clutch lever, the clutch is engaged
and transmits engine power to the tiller and tilling blades begin to
rotate. (See Fig.7)
Figure 6

.13.
Figure 7 Figure 8
● When the user releases clutch lever, clutch will be
disengaged, and the engine power can’t be transmitted to the
tiller, and tilling blades stop rotating. (See Fig 8)
Note: improper adjustment of clutch cable will affect
normal use of the product.
● First confirm tension of clutch cable. Normally the
cable shall have a 4~8mm degree of freedom, if not, please
loosen the locking nut and adjust the cable, and tighten the
locking nut after finishing adjustment. (See Fig.9)
● If necessary, the user may start the engine to check
whether the clutch can engage and disengage properly.

.14.
4. Adjustment of belt tension
●If belt tension isn’t in the normal tension range, it needs adjustment. Please loosen the engine’s 4
mounting bolts(See Fig.10 and Fig.11)。
●After loosen the engine’s 4 mounting bolts, then if belt is too loose, push the engine forward, and if
belt is too tight, move backward the engine till belt tension falls in the normal range, finally tighten
engine’s mounting bolts and connection plate’s mounting bolts. (See Fig.12)

5. Adjustment of accelerator cable
● Idling within normal speed range: l800±l00 Rpm; within high speed range: 3600±50 rmp, and it
can be adjusted using a speed counter.
● Method of confirming speed and adjustment of it

.15.
Figure 12
1. Turn the accelerator valve regulator on the handle frame to the maximum adjustable position without any
load, and check if speed counter shows the speed is 3600±50, and then turn the accelerator valve regulator
to the minimum adjustable position and check whether speed counter shows the speed is 1800±100.
2. If the speed value displayed by the speed counter isn’t within the said ranges, it is necessary to
adjust the gasoline engine.
Steps to adjust the engine:
1）Observe whether connection points of the accelerator cable are loose or have broken off, if so, retighten
them to their original places.
2) Turn accelerator valve regulator on the handle frame to the maximum adjustable position without load,
and then adjust the speed adjusting bolt of the gasoline engine’s accelerator operation mechanism to a
proper position.
3）After long work, the user may adjust the fine-adjusting bolt of the accelerator cable to adjust the engine.

.16.
6. Use the clutch of reverse gear
Warning! Before using the clutch of reverse gear, lower the engine speed.
● By “engage ” and “disengage ”of the clutch of reverse gear, the user can control output of engine’s
power.
● When the user holds tight the clutch lever, the clutch is engaged and transmits engine power to the
tiller and tilling blades begin to reverse rotate. (See Fig.14)
Figure14 Figure15
●When the user releases clutch lever, clutch will be disengaged, and the engine power can’t be
transmitted to the tiller, and tilling blades stop rotating. (See Fig 15)
Note: When using the clutch of reverse gear , especial pay attention to safety . Sure , improper

.17.
adjustment of clutch cable will affect normal use of the product.
