CRAIN 825V Instruction Manual

DOOR CUTTING:
see Figure 15
Open the door to the maxi-

mum, away from the case-
ments. Work from the inside
of the door outward, away
from the hinges. To avoid
splintering veneer doors, it
may be advisable to score
the veneer surface at the de-
sired height of the cut, prior
Figure 15
to using the saw. An applica-
tion of wide masking tape in the cutting zone also helps
reduce splintering, and will protect the saw housing from
scratching the veneer. DO NOT MOVE OR LIFT DOOR
WHILE CUTTING OR KICKBACK MAY RESULT!
NOTE: The maximum thickness of cut is 1 /
5

is adequate for most doors. Check for adequate depth
of cut before starting. Thicker doors may require cuts
from both sides of the door. Take care not to leave a thin
remnant of door on the opposite side, which can easily
break off and crack the veneer. Also, check that the
floor is at the same elevation on both sides of the door,
or additional height adjustment may be required.
The maximum height of cut is one inch. To cut off

higher than one inch, place a flat sheet of plywood
underneath the saw.

Remove any unfinished area at the bottom of the

pocket door with a hand saw, following along in the
pre-established cut.

MASONRY, STONE, OR TILE UNDERCUTTING:

The No. 805 Masonry Blade

is primarily used for cutting
brick. It is not for use on tile
or stone. Use the No. 822
Diamond Blade for cutting
brick, tile or stone.
Figure 17
Masonry, stone, and tile undercutting creates a lot of

dust. We strongly recommend the operator wear a dust
mask and place a light cloth over the air intake on the
motor. This will prolong the life of the saw.
DO NOT use this saw for cutting steel or aluminum. Sparks

can cause fire in the wall behind the door casing.

MAINTENANCE:

If saw is dropped, the blade guard may be bent or otherwise
damaged, restricting full return. Sawdust that accumulates be-
hind the blade guard will cause it to become clogged, especially
drywall dust. Check operation of the blade guard before each
use. Do not use the saw if the blade guard does not operate
properly. When not in use, store saw in the custom carrying
case. The saw motor may run even if the switch malfunctions,
", which
causing the motor to not switch off. Do not use saw if the
8
switch malfunctions. Repair the switch immediately!

WARNING:

Some dust created by power sanding, sawing, grinding,
drilling, and other construction activities contains chemi-
cals known to the State of California to cause cancer, birth
defects or other reproductive harm. Some examples of
these chemicals are:
lead from lead-based paints,

crystalline silica from brick, cement and other

masonry products, and
arsenic and chromium from chemically-treated

lumber.
Your risk from these exposures varies, depending on how
often you do this type of work. To reduce your exposure to
these chemicals: work in a well-ventilated area, and work with
approved safety equipment, such as those dust masks that
are specially designed to filter out microscopic particles.
