ISSUE HT LEAD/SPARK PLUG
Normal spark from HT lead.
1. Carbon build up on spark plug.
2. Electrodes badly burnt/damaged.
3. Incorrect spark plug gap.
No spark at HT lead.
4. HT lead damaged.
5. Ignition coil damaged.
6. Gap between ignition coil and
flywheel to big.
Normal spark from HT lead.
1. Clean carbon build up.
2. Replace spark plug.
3. Adjust the spark plug gap.
No spark at HT lead.
4. Replace HT lead.
5. Replace Ignition coil.
6. Adjust gap.
STARTING DIFFICULTY
(ELECTRIC)
Battery connection.
1. Loose or incorrect battery
connections.
2. Battery not charged.
Battery connection.
1. Check polarity and tighten
connections.
2. Remove battery from machine and
recharge.
MACHINE’S WHEELS TRACK LEFT
OR RIGHT WHILE BEING TOWED
1. Low tyre pressures.
1. Inflate tyres.
THE SHREDDER DOES NOT
SHRED PROPERLY. THE WOOD IS
NOT PULLED INTO THE MACHINE
BY ITSELF.
THE CHIPS DO NOT HAVE THE
SAME SIZE.
1. The blades are worn too much.
2. The diameter of the branches in-
serted into the machine are larger
than 100 mm for HYCH1500E-2 or
70mm for HYCH7070[E]-2
3. The gap between the fixed blade
and the counter-blade is too large,
the correct gap is ½ mm
1. Change or sharpen the blades and
counter-blade.
Note that the blades are sharpened
on both edges so they can be re-
versed.
2. Shut the engine off and remove the
branch that is too thick.
3. Adjust the gap between the blade
and the counter-blade in the slots
THE ENGINE WILL NOT START OR
TURN BECAUSE THE ROTOR IS
JAMMED.
1. The diameter of branches is too
big. There are unacceptable materials
such as stones or metal in the input
tube. A length of branch remains in
the rotor after the engine was last
stopped.
Shut off the engine, remove the spark
plug cap. NEVER under any circum-
stances use your hands to remove
stuck wood.
Reduce size of wood to 100 mm for
HYCH1500E-2 or 70mm for HY-
CH7070[E]-2 or less.
Use a piece of wood to turn the rotor
to remove the material from the rotor
and input tube. If necessary, remove
the cap of the bearing housing and
rotate the rotor axle with a spanner.
If necessary, remove the input or out-
put tube to get access to the rotor.
Check the sharpness of all blades,
have them sharpened or replace as
required.
Make sure all blade bolts are properly
tightened.
