INTRODUCTION

 

Thank you for purchasing this GMC tool. These instructions contain 
information necessary for safe and effective operation of this product 
and will enable you to get the full benefit of its unique features. Keep 
this manual close at hand and ensure all users of this tool read and fully 
understand the instructions prior to use.

SAFETY INSTRUCTIONS FOR IMPACT SHREDDERS 

•  Ensure the supply voltage corresponds with the voltage specified on 

the nameplate. 

•  It is recommended that the shredder should be used with a Residual 

Current Device (RCD) with a tripping current of no more than 30mA.

•  Only use extension cables of a suitable weight for the task. Ideally use 

brightly coloured extension leads that are clearly visible.

• Take care when the blades are in operation.
•  Do not abuse the cable. Never pull the cable to move or disconnect the 

shredder. Keep the cable away from heat, oil, and sharp edges. Ensure 
that the cable is arranged so that it cannot be tripped over, stepped 
on or have heavy weights rested on it. Make sure the cable will not be 
subjected to any damage.

•  Do not attempt to open the casing of the machine, or attempt to modify 

it in any way.

•  The supply cable should only be replaced by an authorised 

 

service agent.

• Do not use the shredder if the cable is damaged or worn.
•   Do not connect a damaged cable to the supply or touch a damaged 

cable before it is disconnected from the supply. A damaged cable can 
lead to contact with live power.

•  Do not touch the blades before the machine is disconnected from the 

supply and the blades have come to a complete stop.

• Keep extension cables away from the blades. 
•  Disconnect the plug from the power prior to clearing a blockage, 

cleaning the machine, if abnormal vibration occurs or if leaving the 
machine unattended.

•  After striking a foreign object, inspect the appliance for damage and 

make repairs as necessary.

• Do not allow children to operate this equipment.

NOTE: It is dangerous to use the machine without the hopper (Fig.5).

OPERATION

 

Electrical safety
•  Before use, check the supply and extension cord for signs of damage 

or ageing.

•  If the cord becomes damaged during use, disconnect the cord from the 

supply immediately. 

• Do not touch the cord before disconnecting the supply.
• Do not use the product if any power cords are damaged or worn.

Safety instructions
  Wear ear protection and safety glasses at all times while operating 

the machine.

  Avoid wearing clothing that is loose fitting or that has hanging  

cords or ties.

•  Only operate the machine in open space (e.g. not close to a wall or 

other fixed object) and on a firm, level surface.

  Do not operate the machine on a paved or gravel surface where ejected 

material could cause injury.

  Before starting the machine, check that all screws, nuts, bolts, and 

other fasteners are properly secured and that guards and screens are 
in place. Replace damaged or unreadable labels.

 Before starting the machine, ensure that the hopper is clear.
• Keep your face and body away from the hopper intake.
  Do not allow hands or any other part of the body or clothing to enter the 

hopper or discharge chute. Keep away from moving parts.

  Keep proper balance and footing at all times. Do not overreach. Never 

stand at a higher level than the base of the machine when feeding 
material into it.

 

 

Always stand clear of the discharge zone when operating 

 

this machine.

•  When feeding material into the machine, be sure to exclude pieces of 

metal, rocks, bottles, cans or other foreign objects.

  If the cutting mechanism strikes any foreign objects or if the machine 

should start making any unusual noise or vibration, shut off the 
power source and allow the machine to stop. Disconnect from supply 
and inspect for damage; Check for and tighten any loose parts. 
Have any damaged parts replaced or repaired with parts having  
equivalent specifications.

•  Do not allow processed material to build up in the discharge zone; this 

may prevent proper discharge and can result in kickback of material 
through the hopper intake.

  If the machine becomes clogged, shut off the power source and 

disconnect from supply before clearing debris. Keep the power source 
clear of debris and other accumulations to prevent damage or possible 
fire. Remember that operating the starting mechanism on engine 
powered machines will still cause the blades to move.

•  Keep all guards and deflectors in place and in good working condition.
 Disconnect this machine from the power source before moving.
•   Shut off the power source and disconnect from supply whenever you 

leave the work area.

  Do not tilt the machine whilst it is running.

STARTING AND STOPPING THE SHREDDER
  Press the On/Off switch (11) to ‘1’ to start the motor, and to ‘0’ to  

stop the motor.

•  Press the ‘circuit breaker’ button if the machine does not start. Ensure 

the machine is connected to the power supply.

  When the motor has been running for a few seconds you can  

begin shredding.

CIRCUIT BREAKER
The circuit breaker will be activated in the following circumstances:
 A build up of shredded material around the cutting disc.
 If the material being shredded is greater than the motor capacity.
 Where there is too much resistance against the cutting blade.
When the circuit breaker has been activated, switch off the shredder and 
disconnect the power supply.
•  Unscrew the reamer knob at the base of the turret and open 

 

top section.

• Remove the debris or obstruction from the cutting area.
• Close the top section and re-tighten the reamer knob.
• Leave motor a few minutes to cool down.
• Reconnect to the power supply and press the circuit breaker button.
• When ready to start shredding, press the on/off switch to ‘1’.
Warning: NEVER slacken off the reamer cover knob without switching 
off and disconnecting plug from power supply.
Warning: The blades will continue operating for a short time after the 
motor is switched off.
Warning:  Keep the motor cooling vents clean of debris and other 
accumulations to prevent damage to the motor or possible fire.

USING THE PLUNGER
A plunger is provided to aid feeding of less bulky material such as small 
twigs, leaves, other garden waste and vegetation into the hopper.
• Load the material into the hopper.
•  Insert the plunger in the chute, pushing the material onto the 

 

blade disc.

•  Wait until all the material has been shredded before adding more 

material.

• Never allow your fingers to enter the chute.
• Never use the tool if the hopper is not fitted.
• Do not over-reach.

MAINTENANCE

 

•  Disconnect from power supply and allow the machine to cool before 

making any inspections, adjustments, etc.

• Always allow the machine to cool before storing.
•  When servicing the blades be aware that, even though the power 

source will not start due to the interlock feature of the reamer, the 
blades can still be moved manually.

•  Never attempt to override the interlock feature of the reamer 

 

cover knob.

•  Check the power cable and any extension cables regularly for 

damage or signs of ageing. Do not use the appliance if any cables 
are damaged.

•  Always clean the machine after use. Remove deposited matter from the 

machine using a brush.

•    Clean the plastic body and plastic parts using soap and a moist cloth. 

Do not use aggressive agents or solvents for cleaning.

•  Never clean the shredder with a jet of water or by rinsing. Make sure 

that no water is allowed to enter into the shredder.

•  Use only the recommended accessories/attachments for 

 

this shredder.

•  If the supply cord needs replacing, the task must be carried out by the 

manufacturer, the manufacturer’s agent, or a power tool repair centre 
in order to avoid a safety hazard.

REPLACING THE BLADES
•  
Ensure that the shredder is switched off and disconnected from the 

mains supply.

• Remove the hopper assembly by unscrewing the reamer knob (10).
•  The blades have two cutting edges. When the blades become worn 

they can be reversed to use the second cutting edge.

• Always wear gloves when handling the blades.
•  Unscrew the two inner hexagonal headed screws and note the position 

of the cutting angle of the blade.

•  Remove the blade and rotate it through 180° and fit the blade to the 

blade disc ensuring that the ground cutting edge is facing downwards.

• Repeat this for the other blade.          

8

When both cutting edges of the blade have become worn they must be 
replaced as a pair. 
The blades can be re-sharpened, but this must be done by an experienced 
person using an oil stone. However, the weight of each blade is critical 
to maintain the balance of the cutting disc. Any imbalance could cause 
damage to the machine and possible injury to the operator.
