Hitachi CD 7SA Handling Instructions Manual page 17

If the piece to be cut off is large in size, care must
be taken to see that the weight of the piece being
cut off does not press on the saw blade. To prevent
the saw blade from being caught between the two
pieces, the piece being cut off should be supported
using a stable bench or braced in place using
wooden supports.
If separate wooden supports are to be used to
support the piece being cut off, when cutting at a
work bench, they should be positioned on a flat
surface and fixed in place. It is dangerous to allow
the work bench to wobble or shift position while
cutting materials with the metal cutting saw.
6. Checking to see that the tipped saw blade is
attached firmly in position
Always check to see that the tipped saw blade is
attached firmly in position. For details, see Page 17:
"Attached and removing the tipped saw blade".
7. Check the lever to see that is properly tightened.
Insufficient tightening of the cutting adjustment lever
may cause personal injury.
Be sure to check that it is firmly tightened.
8. Check to see whether the lower guard moves.
CAUTION
Do not fasten the lower guard permanently in
one position. Make sure that it can move
smoothly. Leaving the tipped saw blade exposed
can result in accidents.
The lower guard is used to prevent the body of the
user from coming into contact with tipped saw
blade. Be sure that the lower guard can be moved
into place and is covering the blade. If for any
reason, the lower guard will not move into position
to cover the blade, discontinue the use of the metal
cutting saw. Please contact an Authorized Hitachi
Service Center for repair.
9. Making adjustments before using the metal cutting
saw
(1) Adjusting the cutting depth (Fig. 1)
CAUTION
If the cutting depth lever is not firmly tightened,
accidents may result. After adjusting the cutting
depth, make sure to tighten the cutting depth
lever firmly.
Loosen the lever and move the base, then you can
adjust the depth of cutting.
(2) Attaching and adjusting the guide (Fig. 2)
Loosen the wing bolt and slide the guide into the
slot at the base. Move the guide left or right to
adjust the location of the cut to be made. After
adjusting the quide, fix it firmly in place by tightening
the wing bolt.
10. Check to see that the brake is functioning properly
This metal cutting saw is designed so that when
the switch is turned off, the brake automatically
functions. If for any reason the brake fails to operate,
please contact an Authorized Hitachi Service Center
for repair.
CAUTION
The metal cutting saw will recoil when the brake
operates.
This can cause the operator to drop the metal
cutting saw, resulting in accidents.
11. Check the power plug
If the power plug is loose or pulls out easily from
the socket, call your local electric repair service and
have the connection repaired.
