Operation
Installing a Chisel.
Chisels come with or without collars. Figure 1 shows
installation of a chisel without a collar (the two included chisels
are without a collar). Figure 2 shows installation of a chisel with
a collar.
Without a Collar:
1.
Pull the retaining ring to the side just far enough to allow
the bit to be inserted, as shown in Figure 1.
2.
Insert the bit. Slide the chisel in as far as it will go.
3.
Pull the retaining ring down approximately 120° until it
contacts the housing. Physically check that the chisel
is secure before operating.
note: If the Chisel Bit doesn’t slide in easily, apply some grease
on the loading end of the Chisel Bit.
With a Collar:
1.
Pull the retaining ring open about 30-40° to the second
engaging position as shown in Figure 2.
2.
Insert the collared chisel.
3.
Return the retaining ring to close to its original position to
lock the chisel in place. Physically check that the chisel
is secure before operating.
Before each use, check the Chisel for cracks or other
damage: never use a damaged Chisel.
Make sure you only use sharp tipped chisels.
Dull tipped chisels can cause unnecessary
chisel movement resulting in tool wear, and
possible injury.
