Working Advice
Raking/Verticutting
Place the product on the edge of the lawn, as close to the main socket as possible. Work away from the main socket. Position the cable to the opposite side (already raked/vertical lawn) at the end of each turn. When raking/verticutting do not overload the motor.
UniversalRake 900:
In case of overload, the speed of the motor drops, and the motor sound changes. In this case, stop, release the start/ stop lever and adjust to a higher working height. Failure to do so could damage the machine.
UniversalVerticut 1100:
The motor is protected by a safety cut-out, which is activated when the blades become jammed, clogged or if the motor is overloaded. When this occurs, switch the product off.
The safety cut-out is only reset when the start/stop lever is released.
Pull the mains plug, remove any blockages and wait one minute before restarting the product so that the safety cut out can reset itself.
▶ Always wear gardening gloves when handling or working near the sharp tines/blades. Note: When waiting for a reset of the safety cut out and actuating the start/stop lever too early with the product plugged into the socket outlet, the reset time of the safety cut out will increase.
If the product cuts out again, increase the working height or postpone use until conditions improve. Please refer to the Trouble Shooting Chart” and “Raking/Verticutting Tips”.
Raking/Verticutting Tips
Optimum conditions for raking/verticutting are when the grass is short and slightly moist. Raking or verticutting the lawn, when the soil is very soft or hard, can damage it and cause the product to collect poorly.
– Kill moss with a commercially-available moss killer before raking/verticutting.
– Start the product at the highest working height and lower it as required.
– Rake/Verticut the lawn in the one direction, then proceed at right angles a week later until the whole lawn has been completed.
– Depending on the condition of the lawn, raking/verticutting moss and dead plant parts can lead to ragged and bare patches.
Note: In conditions with excessive tree debris (e. g. leaves, twigs, etc.), first clear the surface by using the product with the working height set to 3 or 4.
For best results mow the lawn before reseeding. Promote the spread of grass into bare and weak areas with good quality lawn seed after raking/verticutting. Allow fresh grass seed to root and establish before fertilizing, where necessary water to prevent fresh seeds from drying out. Ideal times for raking/verticutting are spring and late autumn. Lawns can also be maintained by raking/verticutting on a higher setting after every six cuts.
