OPERATION

Setting cutting height (See fig. L)

If you wish to change the cutting height, push the adjusting lever first to make it out of the 
tooth and then push the lever to the desired position.

  

WARNING:

Never operate the adjusting handle roughly.

Removing and inserting the battery pack

Insert the battery pack. (See fig. M)

Align the battery pack with its compartment of the tool. Push the battery pack into the tank 
until you hear a click. This means the battery pack has been locked in position, then close the 
battery pack tank cover.

Removing the battery pack from the tool (See fig. N)

Open the battery pack tank cover. Pull the battery pack release button, the battery pack will 
come out automatically.

NOTE: Safety-Key (See fig. O)

This lawnmower is fitted with a safety key; this prevents the accidental start up of your 
cordless lawnmower.
The safety key has been designed to totally disable the lawnmower when it is removed.

Switching on and off (See fig. P)

Switch on: 

1. Press and hold the safety button on the side of the switch box with one hand. 
2. Pull the switch bar towards the handle and hold it with the other hand.

Switch off: 

Release the switch bar.

NOTE: 

Do not continue to press the start button after an automatic shut-off of the machine, 

this will lead to battery damage.

  

WARNING:

When the motor has been switched off, the blade will continue to run for several seconds. Do 
not touch the underside of the mower until the cutter has come to a complete standstill!

Operating the lawnmower

Operation on a slope:

Slopes increase the risk of slip-and-fall accidents, which can result in severe injury. Always be 
sure of your footing on slopes. Operation on slopes requires extra caution. If you feel uneasy 
on a slope, do not mow it.

Do:

-   Mow across the face of slopes, never mow up and down. Exercise extreme caution when 

changing direction on slopes.

-   Watch for holes, ruts, rocks, hidden objects or bumps which could cause you to slip or 

trip. Tall grass can hide obstacles.

Do not:

-   Do not mow near drop-offs, ditches or embankments; you could lose your footing or 

balance.

-   Do not mow slopes greater than 15 degrees.
-   Do not mow on wet grass. Unstable footing could cause you to slip.

Mower overload protection

To prevent overload conditions, do not try to cut too much grass at one time. Slow down your 
cutting pace or raise the cut height. Your mower has built-in overload circuit protection. When 
the mower is overloaded, the motor will stop. Switch the mower off and check to see if grass 
has collected beneath the deck and clear it if necessary, then restart the mower.

Battery high temperature protection

The battery pack will generate heat during operation. The heat dissipates slower in hot 
weather. If the battery temperature exceeds more than 70 

o

C during operation, the protection 

circuit will immediately turn off the mower to protect the battery pack from damage. Release 
the bail handle, wait until the battery pack cools down and then restart the mower.

Function of full indicator (See fig. Q)

If the grass bag is empty or it is not filled with grass, the grass full indicator will be open. 
If the grass bag is filled with grass the grass full indicator will be closed. 

Emptying the grass bag 

As soon as the grass bag indicator closes while you are mowing this means that it is time to 
empty the grass bag.

NOTE: 

Before taking off the grass bag, switch off the engine and wait until the blade has 

come to a complete stop. 
To take off the grass bag, use one hand to lift up safety flap and the other to grab onto the 
carry handle. The safety flap automatically falls down after removing the grass bag and closes 
off the rear chute opening. 
Empty out the grass bag then refit to machine.

NOTE: 

If any grass residue is caught in the discharge chute, clean it using a brush. Do not 

remove grass debris in the mower casing or on the blade by hand or with your feet. Instead 
use suitable tools such as a brush or broom. To ensure that the cut grass can be collected 
into grass bag, the discharge opening and inside the mower casing must be cleared of any 
blockages.
