Site Considerations

Consider the existing and anticipated needs, the
size of the material to be held in the vise, and the
space for auxiliary stands, work tables or other
machinery when establishing a location for your
new vise. See Figure 2 for the minimum working
clearances.

Introduction
Workbench Load
The H8188 Multipurpose Vise weighs 22 lbs.
Some workbenches may require additional rein-
forcement to support both the vise, the workpiece,
and any hammering or prying forces that may be
applied to each.
This vise is not a toy. DO NOT use as a
crushing tool and never clamp a contain-
er with compressed or explosive contents.
Serious injury may occur if this vise is used
incorrectly.

Mounting
The multipurpose vise must be mounted to a work-
bench to avoid accidental tipping. If you intend to
use the vise for portable applications, mount it to
a heavy metal or plywood base (at least 1" thick)
that is wide enough to prevent tipping or rocking
during use, then clamp the base to a workbench
or table.
To mount the multipurpose vise:
1. Place the vise in its chosen location, making
sure that all four corners of the vise sit flat on
the mounting surface.
2. Transfer the mounting pattern directly from
the vice to the workbench by marking though
the vice mounting holes.
3. Attach the vise to the workbench using one of
the methods outlined below.
Note: DO NOT overtighten the mounting
bolts or you may crack the vise base.
The strongest mounting option is a "Through
Mount" (Figure 3) where holes are drilled all the
way through the workbench, and hex bolts, wash-
ers, and hex nuts are used to secure the vise to
the workbench.

Another option for mounting is a "Direct Mount"
(Figure 4) where the vise is simply secured to the
workbench with a lag screw.

4. Check the stability of the mounted vise to
make sure it is stable enough to be used
safely.
5. Always make sure the vise is bolted or
clamped to the workbench or table before
use.
Operations
To maximize the life of your vise:
• Do not use cheater pipes on the handles to
increase tightening force.
• Do not heat or weld on the vise.
• Do not store the vise in wet or damp loca-
tions.
• Only use the anvil for light tapping and
workpiece shaping. Do not use large ham-
mers and avoid hammering directly on the
jaws.
• Do not pry on clamped materials in such a
way that may bend or break the vise.
• Do not hammer the levers tight.
• When loosening the jaws, make sure your
hands will not hit the workpiece, workbench
or vise when the handle breaks free.
• Every few years, disassemble, clean, and
lubricate the vise using lithium grease.

A. Jaw Opening Scale: Can be used to approx-
imate the jaw opening size.
B. Anvil Face: Provides a strong and stable
surface for hammering malleable materials
with a small hammer.
C. Rotating Jaws: Allow 360° of movement and
are locked by tightening of the jaw. Scale
provides approximate angle readings through
180°.
D. Standard Jaws: Clamp flat-edged work-
pieces.
E. Main Vise Handle: Used to clamp and lock
the jaws.
F. Base Locking Levers: Allow the base to
be swiveled 360° for maximum flexibility and
locked for stability.
G. Mounting Base: Used to attach the vise to a
workbench or other suitable surface.
H. Pipe Jaws: Clamp pipes and other cylindri-
cal workpieces. For easier access, they can
be positioned at the top by rotating the main
jaws.
I. Cut Jaws: Clamp irregularly shaped objects
or pieces of pipe too short to be clamped by
the pipe jaws.
