7. “2 IN 1”
These lawn mowers can be retrofitted from its normal function, based on the application purpose:
From lawn mower with rear discharge to mulching mower
What is mulching?
When mulching, the grass is cut in one working step, then finely chopped and returned to the grass
strip as natural fertilizer.
Hints for mulch-mowing:
- Regular cut-back by max.2cm form 6cm to 4cm grass height.
- Use a sharp cutting knife - Do not mow wet grass
- Set max. Motor speed
- Only move at working pace
- Regularly clean mulching wedge, housing inner side and mowing blade
Starting Operation
ONE: Retrofitting for mulching mower
WARNING:
only with a stopped motor and standstill cutter.
1. Raise the rear cover and remove the grass catcher.
2.Push the mulching wedge into the deck. Lock the mulching wedge into the opening on the deck.
(Fig. 9A/ Fig. 9B).
3. Lower the rear cover again. (Fig. 9C).
TWO: Mowing with the grass catcher
WARNING:
only with a stopped motor and standstill cutter.
For mowing with the grass catcher, remove the mulching wedge and mount the grass catcher.
1. Removing the mulching wedge:
- Lift rear cover and remove the mulching wedge.
2. Mount the grass catcher:
- To fit: Raise the rear cover and hitch the grass catcher on rear of mower.
- To remove: Grasp and lift the rear cover, remove grass catcher.
WARNING:
Disconnect the electric cord from the power supply.
8. SAFETY PRECAUTIONS
a) Always operate with the deflector or grass catcher in the correct position.
b) Always stop the motor before removing the grass catcher or adjusting the height of cutting posi-
tion.
c) Before mowing, remove all foreign objects from the lawn which may be thrown by the machine.
While mowing, stay alert for any foreign objects which may have been missed.
（
Fig.10A
）
d) Never lift the rear of the mower while starting the motor or during normal operation.
（
Fig.10B
）
e) Never place your hands or feel underneath the under pan or into the rear discharge chute while
the motor is running. (Fig. 10C).
9. OPERATING INSTRUCTIONS
9.1. Starting
Switch on the isolator key.
Start the motor as follows( Fig.11):
a) Press the safety push-button (1).
b) And meanwhile, press any switch button (2) (There are four buttons) , and keep it in grasp.
Lift the front of the machine and switch off isolator key while crossing gravel or roads surface.
If you release the switch button, the motor will stop.
CAUTION!
The blade starts turning as soon as the motor is started.
WARNING!
Cutting elements continue to rotate after the motor is switched off.
CAUTION!
your mower is designed to cut normal residential grass of a height no more than
250mm.
Do not attempt to mow through unusually tall dry or wet grass (e.g. pasture)
or piles of dry leaves.
9.3 LED
Please refer to the following table for the meaning of LED display. (Fig. 13A/ Fig. 13B).
9.4 For the best results when mowing
Clear lawn of debris. Be sure that the lawn is clear of stones, sticks, wire or other foreign objects
which could be accidentally thrown out by the mower in any direction and cause serious personal
injury to the operator and others as well as damage to property and surrounding objects. Do not cut
wet grass. For effective mowing do not cut wet grass because it tends to stick to the underside of
the deck preventing proper mowing of the grass clippings. Cut no more than 1/3 the length of the
grass. The recommended cut for mowing is 1/3 the length of the grass. Ground speed will need to
be adjusted so the clippings can be dispersed evenly into the lawn. For especially heavy cutting in
thick grass it may be necessary to use one of the slowest speeds in order to get a clean well mowed
cut. When mowing long grass you may have to cut the lawn in two passes, lowering the blade ano-
ther 1/3 of the length for the second cut and perhaps cutting in a different pattern than was used the
first time. Overlapping the cut a little on each pass will also help to clean up any stray clippings left
on the lawn. The mower should always be operated at full throttle to get the best cut and allow it to
do the most effective job of mowing. Clean underside of deck. Be certain to clean the underside of
the cutting deck after each use to avoid a build-up of grass, which would prevent proper mulching.
Mowing leaves. The mowing of leaves can also be beneficial to your lawn. When mowing leaves
make sure they are dry and are not laying too thick on the lawn. Do not wait for all the leaves to be
off the trees before you mow.
WARNING:
if you strike a foreign object, stop the motor. Switch off the isolator key, thorou-
ghly inspect the mower for any damage and repair the damage before restarting and operating the
mower. Extensive vibration of the mower during operation is an indication of damage. The unit
should be promptly inspected and repaired.
10. BLADE
The blade is made of pressed steel. It will be necessary to reshape it frequently (with a grind wheel).
Ensure that it is always balanced (an unbalanced blade will cause dangerous vibrations). To check
for balance, insert a round rod through the central hole and support the blade horizontally. A balan-
ce blade will remain horizontal. If the blade is not balanced the heavy end will rotate downwards.
Reshape the heavy end until the blade is currently balanced. To remove the blade (1), unscrew the
blade screw (2).
and replace any parts, which are damaged.
When reassembling, make sure that the cutting edges face in the direction of the motor rotation.
The blade screw (2) must be torque to 20N.m.
WARNING:
For service, replace the blade with DAYE blade: DAYE 263003498
WARNING:
Remove the battery from the machine.
WARNING:
Protect hands by using heavy gloves or a rag to grasp the cutting blades
when replace the blade.
11. MAINTENANCE AND CARE
WARNING:
Before performing any Maintenance or cleaning work, Always remove batterys
and switch off the isolator key!
Do not spray the unit with water. Ingress of water may destroy the switch and the electric motor.
Clean the unit with a cloth, hand brush, etc.
Expert inspection is required, do not make any adjustment by yourself, must contact to custo-
mer Service centre:
a) if the lawn mower strikes an object.
b) if the motor stops suddenly
c) if the blade is bent (do not align!)
d) if the motor shaft is bent (do not align!)
e) if a short-circuit occurs when the cable is connected.
f) If the V-belt is defective.
h) Use only manufacturer’s recommended replacement parts and accessories.
12. TROUBLESHOOTING
WARNING:
before performing any maintenance or cleaning work, always remove batteries
and switch off the isolator key! Only with a stopped motor and standstill cutter.
CAUTION!
Faults which can not be rectified with the aid of this table may be rectified by a
specialist company only (customer service centre).
13. ENVIRONMENTALLY FRIENDLY DISPOSAL
According to EU directive 2012/19/EU on electric and electronic equipment and its implementation
into national law, all electric tools must be separately collected and environmentally friendly recy-
cled. Alternative disposal: If the owner of the power tool does not return the tool to the manufactu-
rer, he is responsible for proper disposal at a designated collection point that prepares the device
for recycling according to national recycling laws and regulations.
This does not include accessories and tools without electric or electronic components.
