Using The Machine; Changing The Blade Speed; Rate Of Feed Of Work To Blade; Safety Cut Off Switch Cover - Burgess BK3 Specification And Operating Instructions

Changing the blade speed
Your Bandsaw is supplied in the high
speed mode for cutting wood and
softer materials, and for finishing
operations in wood or metal using the
sandingflinishing belt. For operations
involving mild steel, alloys etc. the slow
speed mode is required to avoid undue
wear of the blade and

Using the machine
Rate of feed of work to blade
Rates of feed vary with the matenai being
cut and its thickness. Always allow the
blade to do the work and never apply
undue pressure sufficient to distort the
blade. A little experience will indicate the
correct rates of feed for materials of dif-
ferent hardness and thickness. Forcing
the rate of feed will shorten the life of your
bandsaw blades.
Safety Cut off Switch Cover
Both Bandsaws feature a dual purpose
safety cut oH/dust cover on, the switch.
To SWitch the machine on the cover
must be raised and the switch
depressed. However, the machine may
be switched
oH
