B. A cold machine is forbidden to do heavy load work immediately after it is started, especially
for new machines or overhauled machines.
C. Pay attention to the oil levels of engine and gear box. Refill the engine oil when it is not
enough
D. It is not allowed to cool the engine by watering
E. Be cautious about the machine’s tilting when farming.
F. The machine mounted with revolving farming blades is forbidden to run on beach or pebbles.
G. After using the power tiller for farming, please clean dirt, weeds and smear on the machine
to keep it clean.
H. Clean the sponge or the wire mesh in the air cleaner and change the engine oil frequently
Chapter Five Maintenance
When the power tiller is under operating, due to the changes of running, abrasion and loading,
bolts loosening and parts wearing are inevitable, which will lead to the system malfunction, high
oil consumption and other failures of the machine. To reduce the trouble possibility, it is better to
maintain the power tiller regularly and strictly to keep the machine in a good condition and to
extend its working life.
Ⅰ
Running -in
A. For engine running-in, please refer to the engine instruction manual
B. For a new or overhauled power tiller, please drain all the lubricant from the gear box and
engine crankcase immediately after working for 1 hour under no load or 5 hours under light load.
Then refill in engine oil according to 4 clause chapter 3 for a four- hour running- in before the
machine can be operated.
Ⅱ Maintenance
A. Normal maintenance (before and after every operation)
a) Listen and observe if there are any abnormalities (such as abnormal sound, overheating and
bolt loosening, etc)
b) Check if there is oil leakage in engine, gear box and stepping box
c) Check if the oil level in engine and gear box is between the dipsticker limitations.
d) Clean the mud, weeds and smear on the machine in time after operating.
e) Keep a good farming record
B. The first rate maintenance (every 150 working hours)
a) Do all the things listed for normal maintenance.
b) Clean the gear box and step box, and change the engine oil
c) Check and adjust the clutch, shift system and reversing system.
C. Second rate maintenance (every 800 working hours)
a) Do all the things listed in first rate maintenance.
b) Check all the gears and bearing, replace with new ones if serious abrasion is found.
c) Replace with new ones if damages are found with revolving farming blades, connection bolts or
other parts.,.
D. Technical overhaul (every 1500-2000 working hours)
a) Take the power tiller to your local special service center for overhaul.
b) Please ask professional serviceman to check the friction piece and clutch.
