HEINRICH Grip-Master 3-SV User manual

OPERATION:
Grip-Master units are adjusted for proper holding pressure at
the time of assembly. Increased pressure can be obtained by a
slight- counter-clockwise turn of the adjusting screw (after first
loosening the cover plate). Decrease pressure by a clockwise
turn of the adjusting screw. The amount of turn necessary can
be determined by the results obtained. The maximum pressure
setting is not necessary for adequate holding power. If it is
difficult to depress the locking lever, the setting is on the heavy
side. When just normal hand pressure is required to lower the
lever to horizontal position, this is the proper setting of the
adjusting screw. It is best when re-setting the locking
mechanism to adjust to absolute maximum, then reduce
pressure down to about middle range for ease of operation.
Turning too far in either direction will cause the center bar to
lock. For maximum machining accuracy, clamp vise to the
work table using the two side lugs.
MAINTENANCE:
The locking mechanism of Grip-Master units must be oiled
occasionally in the oil hole provided therefor. Keep bars and
locking mechanism free from dirt and chips.
If a Grip-Master unit becomes inoperable, disassemble the
locking mechanism in this manner:
1. To remove center bar (3) of a vise, place handle in locked
position and remove the shoulder screw which attaches it to
the movable jaw. (On models prior to 1958, the center bar was
press fit into the movable jaw; bar can be removed by inserting
a 1/4" pin in the knock-out hole in the movable jaw casting.)
2. Place handle lever (5) in vertical position.
3. Remove screws and cover plate (20).
4. Remove spring pressure on locking ring (6) by turning
adjusting screw (17) counter-clockwise.
5. All locking mechanism parts can then be removed.
Clean and check each part for wear or damage. Replacement
parts are available for immediate shipment from factory stock,
or you may order through your local Heinrich distributor.

Note 1. Price not shown, as replacement body castings are not available. View shown is 4-GM with side extension. Models 3-SV, 6-SV and 8-SV do not have
side extensions. 3-TS and 4-TS have both sides ground at right angles to jaw inserts.

(Cont. from prev. page) pressure before replacing locking
plate. To assemble Pumping Action "PA" Locking
Mechanisms, the following steps must be carefully followed:
1. Insert crank (10), keeping handle lever (5) in vertical position
during entire assembly.
2. Insert rear portion of adjusting screw (18), screwing same in
as far as it will go.
3. Place the holding ring (7) behind crank so that the pin
extending from the crank fits into the slot of the holding ring.
4. Insert center bar (3) through the holding ring far enough so
that the holding spring (9) can be slipped on.
5. Insert front portion of the adjusting screw (19) as far as it will
go.
6. Insert locking ring (6) and push center bar through same.
7. Insert locking spring (8), locating same correctly in relation
to the center hole.
8. Adjust both adjusting screws until the rear portion (18)
makes contact with the holding ring and the front portion (19)
makes contact with the locking ring.
9. Push center bar through entire unit.
10. Turn adjusting screw front portion (19) a 3/4 turn clockwise,
and adjust rear portion (18) until the bar moves freely – making
sure that the handle lever is in vertical position against stop.
11. Adjust forward portion of adjusting screw (19) until desired
pressure is obtained.
