5. Only operate the electric garden tool when visibility is good.
6. Whilst the motor is powered do not open the rear discharge flap or tip the machine to expose the
blades or tines.
7. Take extra care when operating on slopes and even ground. When changing direction on slopes
take additional care to avoid slips or falls.

11. Operate the powered garden tool at a walking pace only. Always ensure that you have secure
foothold when working.
12. When leaving the machine unattended for any time, disconnect the mains power supply plug.
Similarly, whilst transporting the powered tool from one work area to another disconnect the power
and put the wear compensation lever in the transport position. See section 5.
13. If the scarifier comes into contact with stones, twigs, branches or other hard surfaces stop
operation immediately. Disconnect the mains power, remove any obstructions and inspect the
machine for damage. Do not operate the powered tool if it is damaged. Repair the machine before
operating again.

Electrical safety:
1. Keep the scarifier and any extension cables away from the aerator cylinder and the scarifier
tines to avoid damage to the cable.
2. Do not allow the machine or its connectors to be become wet. Do not use whilst it is raining.
3. Be considerate to your neighbours when you operate the garden scarifier and abide by the local
regulations regarding designated quiet times.
4. Regularly ensure that cables and connectors are not damaged and check for signs of wear and
tear. Replace as required.
5. Disconnect the mains plug immediately if the cables, switches or connectors are damaged.
6. Only use suitable waterproof type connectors for external extension cables. Extension cables
should meet the requirements of DIN VDE 0620 and have appropriate cable cross-sections for the
application. Your local dealer will be able to recommend suitable outdoor extension cables.
7. Use a residual-current device with a rating of 30mA or less. Ask your local dealer for details.

3.Assembly

rotating before switching “on” again.
Do not rapidly switch on and off.
Starting:
1. Press and hold the safety button ①
2. Squeeze the switch lever ②towards
the main handle
3. Release the safety button ①
To Stop:
1. Stopping: Release the switch lever ②
Danger!
The aerator cylinder can cause injuries!
Prior to maintenance unplug from the mains
and wait until the Aerator drum has stopped.
Wear working gloves for performing
maintenance.
The Aerator should be cleaned after each
time it is used. Remove grass and deposits
from wheels, aerator cylinder and hosing.
Risk of injury and physical damage!
Do not clean Aerator under running
water (particularly under high pressure ).
Do not use hard or pointed objects for
cleaning the Aerator.

Adjusting for wear:
The Aerator is subject to wear in use due
to the way in which it works. The more
intensively the Aerator is used, the greater
the wear on the knives.
Hard or very dry ground accelerates wear
as does excessive use of the Aerator.
If the results of your work with the Aerator
become increasingly worse due to knife
wear, the aerator cylinder can be
adjusted by selecting different positions on
the lever.
The aerator cylinder has 4 adjustment
positions:
·Transport position 1
·Aerating position 2
·Aerating position 3
First adjustment position after knife wear
(aerator cylinder lowered by 3 mm)
·Aerating position 4 ：
Second adjustment position after knife
Wear
(aerator cylinder lowered by afurther 3mm)
Push wear compensation lever gently
away from the housing and move to the
position required.
Note: Wear adjustment is not used
for height adjustment. Adjustment
of the aerator cylinder without
visible wear can cause damage to
the aerator cylinder or overload the
motor.

6.Trouble-shooting
Replacing aerator cylinder:
Danger!
The aerator cylinder can cause injuries! Prior to rectifying
faults, unplug from the mains and wait until the aerator
cylinder has stopped. Wear working gloves when
rectifying faults.
If the aerator cylinder is in wear adjustment position 3
and is worn, the aerator cylinder must be replaced.
1. Unscrew two screws ⑮on the underside of the
hosing.
2. Lift the Scarifier blades cylinder ⑯at an angle and
pull away the drive shaft.
3. Remove the bearing shell ⑰from the Scarifier
blades cylinder ⑯
4. Push the bearing shell ⑰on to the new Scarifier
blades cylinder ⑯
5. Push the new aerator cylinder ⑯on to the drive
shaft in such a way that the pin ⑲is inserted in the
gap in the drive shaft ⑳
6. Screw the bearing shell ⑰to the underside of the
housing without tightening too much.
7. Replace the aerator cylinder with the scarifier
cylinder ⑱in the same way as above.

7 Using the SA32E
For operating convenience, it may be best to start scarifying at a point close to the power supply
and to work away from the supply. Use the tool at a right angle from the power supply and place
the power cable to side which has already been scarified.
Warning：When scarifying or aerating do
not allow the motor to labour particularly in
heavy conditions. When the motor labours
the speed of the motor drops and you will hear a change
in the motor sound, when this occurs stop operating,
release the switch lever and raise the height of cut.
Failure to do so could damage the machine.
NOTE: the motor is protected by a safety cut out which
is activated when the blade becomes jammed or if the
motor is overloaded. When this occurs, stop the
machine and remove the plug from the power supply.
The safety cut out will only reset when the switch lever
10 is released. Clear any obstruction and wait for a few
minutes for the safety cut out to reset before continuing
to working. At this time do not operate the switch lever 10 as this will prolong the reset time of the
safety cut out. If the mower cuts out again, increase the operating height to reduce the load on the
motor.
