Tractive Support 

 

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. The guards come in 5 different sizes, Ø 800 (32”), Ø 1000 (40”), Ø 1200 (48”), Ø 1600 (63”)

 

and Ø 

2000 mm

 (78”)  

 
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. For 
example, in a situation 
when 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. 

 

Normally the function of the 
blade guard is to protect 
the operator and the 
surrounding area from the 
water and loose material which is cut away by the blade and thrown out of the cut. To give any 
protection at all, 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.
