Mounting the blade guard 

 
New safety regulations means that greater emphasis has to be put on safety, and therefore on the 
blade guards, and these can now, thanks to a new and better design, remain on the machine at all 
times. A prerequisite to achieve any level of protection is that the guard is fitted to the machine at 
all times. For the 6-12HF the guards are available in three different sizes, Ø 800 (32”) , Ø 1000 
(40”), and Ø 1200 (48”) for normal and flush cutting. Fully covering “parallel” blade guards are also 
available for use together with a parallel blade guard guide.  
 
The blade guard is automatically controlled by the movements of the saw arm, and the operator 
does not have to adjust the guard while the machine is running. The guards consist of three main 
pieces, a middle main piece and two detachable side pieces. A pivoting shield is provided to 
contain overspray from the blade. It should be adjusted before starting to cut. 
  
The guard is mounted by entering the grooved bushing into the C-profile on the guard and then 
pushing the T-bar with the two holes in it on to the two tapered bolts on the saw arm. Then the 
safety lock is slid down and secured with an 8 mm (5/16”) Allen key. To remove the guard, first 
remove the safety lock and press the two locking screws on the guard together and take off the 
guard. 

 

Warning!  The blade guard 
has many functions. The 
most important one is to 
protect the operator and other 
persons from accidental 
injury. In a situation when, for 
example, the operator or 
someone else accidentally 
falls against the machine, the 
guard is there to as well as 
possible protect against 
contact with the running 
blade. In other potentially 
dangerous situations, for 
example if a cracked or faulty 
blade is used, or if the blade 
is not properly fitted, or the 
quick release coupling is 
improperly used, the guard is 
there to reduce the damage 
done by a blade. 
 
The blade guard must be 
mounted at all times when 
the blade is rotating under 
power. The instructions 
above must always be 
followed. Failure to follow this instruction may result in serious personal injury or death.  
 
Warning! The blade guard may not be fitted or removed before the two power cords are 
disconnected from the saw. This rule must always be followed to eliminate that the blade 
motor is started by accident or the arm or chassis moved when the operator is working on 
the saw head. Failure to follow this instruction may result in serious personal injury or death.
