16 / CUTTERS EDGE FIRE RESCUE SAWS

IMPORTANT

Always operate the saw with a minimum of two

people on the roof for safety. One should operate

the saw and the other act as backup and as eyes

and ears for the operator.

Always wear full protective gear, along with a face

shield or goggles.

Sound the roof for the safest operator position.

Select and prepare an alternate escape route.

Position yourself properly and prepare to cut.

ONE-STEP STARTING PROCEDURE

Since you have properly warmed up the saw, you can start

it now using the One-Step Starting Procedure. After posi-

tioning yourself properly, securely holding the saw in place,

simply pull the starter handle upward (Fig. 22). The saw will

start and you will be ready to cut.

CUTTING

Never cut with the saw directly in line with your

body or across your body.

When ready to begin cutting, choose a position that is safe

and comfortable. Cut with the saw held to one side of

your body, locking your top elbow, if possible. Avoid cutting

with the saw directly in line with or across your body.

PENETRATION CUT

To begin your penetration cut, hold the saw at an angle of

approximately forty-five degrees to the roof (Fig. 23). This

positions the highest number of cutters in contact with the

roof surface for optimum penetration speed.

Fig. 23. Penetrate at approximately 45 degrees.

Attempting to penetrate with too high an angle

may cause kickback, while penetrating with too

ow an angle will actually increase penetration

me and cause unnecessary wear to the cutters.

Plunge the bar in aggressively for penetration, but don't

penetrate any deeper than necessary. This will prevent the

nadvertent cutting of hidden dangers, such as rafters,

wiring or braces.

After you have penetrated the roof surface, increase the

angle of your saw up to ninety degrees. This places a

greater number of cutters in contact with the broad surfaces

of the rafters, increasing your sensitivity of feel.

With practice you will get a feel for boring through the roof

surface. If it feels like it is taking too long to penetrate, you

may be directly on a rafter. Simply move your cut over a few

nches and begin to cut again.

"ROLLING THE RAFTERS"

When you feel a rafter, pull the saw up and allow it to cut

only the roof decking as you roll over the rafter (Fig. 24).

Then return to your previous depth of cut until you

encounter another rafter to roll (Fig. 25). This preserves roof

ntegrity and provides you with another measure of protec-
