MAINTENANCE

POWER CABLE MAINTENANCE
If the power cable needs replacing, the 
task must be carried out by an electrician 
or a power tool repairer in order to avoid a 
safety hazard.

CHANGING THE BLADE

Warning: 

Always ensure the Mitre Saw 

is switched off and the plug is removed 
before performing any adjustments or 
maintenance procedures.

Caution: 

Never try to use a blade that 

is larger than the stated capacity of the 
Mitre Saw. It might come into contact 
with the blade guards and risk personal 
injury or damage to the Mitre Saw. This 
will not be covered under warranty.

!

!

Caution: 

Never use a blade that is too 

thick to allow the outer blade washer 
to engage with the flats on the spindle. 
It will prevent the blade screw from 
properly securing the blade onto the 
spindle.
