cutting attachment or an incorrectly sharpened blade
increases the risk of blade thrust.

9.1 Cutting attachment

Grass blades and grass cutters are intended for cutting
coarse grass. (Fig. 8)
A trimmer head is intended for trimming grass. (Fig. 9)
General rules
- Only use cutting attachments with the guards we
recommend! See the chapter on Technical data.
- Keep the teeth of the blade correctly sharpened! Follow
our instructions and use the recommended file gauge.
An incorrectly sharpened or damaged blade increases
the risk of accidents.
- Check the cutting attachment for damage or cracks. A
damaged cutting attachment should always be replaced.

9.2 Sharpening grass cutters and grass blades

- Sharpen blades and cutters using a single-cut flat file.
- Sharpen all edges equally to maintain the balance of
the blade.
Always discard a blade that is bent, twisted,
cracked, broken or damaged in any other way.
Never attempt to straighten a twisted blade so
that it can be reused. Only use original blades of the
specified type.

9.3 Trimmer head

IMPORTANT Always ensure the trimmer cord is wound
tightly and evenly around the drum, otherwise the machine
will generate harmful vibration.
Only use the recommended trimmer heads and trimmer
cords. These have been tested by the manufacturer to
suit a particular engine size. This is especially important
when a fully automatic trimmer head is used. Only use
the recommended cutting attachment. See the chapter on
Technical data.
Smaller machines generally require small trimmer heads
and vice versa. This is because when clearing using a
cord the engine must throw out the cord radially from the
trimmer head and overcome the resistance of the grass
being cleared.
The length of the cord is also important. A longer cord
requires greater engine power than a shorter cord of the
same diameter.
Make sure that the cutter on the trimmer guard is intact.
This is used to cut the cord to the correct length.
To increase the life of the cord it can be soaked in water
for a couple of days. This will make the line tougher so that
it lasts longer.
CUTTING EQUIPMENT (LONG REACH HEDGE
10.
TRIMMER)
To ensure good cutting results it is important that the
contact pressure between the blades is correct. The
contact pressure is adjusted by turning the screws on the
underside of the bar clockwise as far as they will go. Then
turn the screws anticlockwise a 1/4 turn.

Lock the screws using the locking nut on the top of the
bar. Check that the screws are loose enough to allow the
washers under the screw heads to slide sideways.
When the blades are correctly adjusted the play between
the blades should be 0,2–0,4 mm, measured at the screws.
The edges of the blades are too hard to be filed. Dull
blades should be sharpened using a grinder.
Replace the blades if they are bent or damaged.
OPERATING INSTRUCTIONS
11.

11.1 Prepare the machine

11.1.1 Assembling the Front handle
Fit the front handle absorber (A) on the rear tube (C).
While aligning the hole (B) on the front handle absorber,
the position pin (F) on the barrier (E) and one position hole
(D) of three on the rear handle, fit the barrier on the rear
handle and insert the position pin into the position hole on
the rear handle. Make sure the barrier on the left side of
the machine. (Fig. 10)
Push down the front handle (G), and then turn four screws
(H) clockwise to tighten the front handle securely. (Fig. 11)
11.1.2 Connecting the tube (Fig. 12)
Align the hole (A1) on the front tube (A) and the lock pin (B).
Then, Pull out the Lock pin, and while inserting the front
tube in the connector (D) to the end. After loosened the
lock pin, it will return to its original position automatically,
and insert into the hole on the front tube.
Make sure the front tube can't be rotated after the lock pin
came back to its original position. Turn the lock knob (C)
clockwise to tighten the front tube securely.
11.1.3 Fitting blades and trimmer heads
When fitting the cutting attachment it is
extremely important that the raised section on
the top clamping plate/support flange engages
correctly in the centre hole of the cutting
attachment. If the cutting attachment is fitted
incorrectly it can result in serious and/or fatal
personal injury.
Never use a cutting attachment without an
approved guard. See the chapter on Technical
data. If an incorrect or faulty guard is fitted this
can cause serious personal injury.
11.1.4 Fitting the guard extension
- The guard extension shall always be fitted when using
the trimmer head and combination guard. The guard
extension shall always be removed when using the
grass blade. (Fig. 13).
- Hook the blade guard/combination guard onto the fitting
on the shaft and secure with three bolts. (Fig. 13).
- Enter the guard extension guide in the slot of the
combination guard. Then click the guard extension into
position on the guard with some claws. (Fig. 14).
- The guard extension is removed easily using a
screwdriver, see illustration. (Fig. 15)
