IMPORTANT -IACAUTION I
This manual contains important information for the correct installation, operation and maintenance of
the equipment described herein. All persons involved in such installation, operation, and maintenance
should be thoroughly familiar with the contents. To safeguard againstthe possibility of personal injury
or property damage, follow the recommendations and instructions of this manual and keep it for
further reference.
IAWARNING!
The equipment shown in this manual is intended for industrial use only and should not be used to lift,
support, or otherwise transport people, or to suspend unattended loads over people.

lA-WARNING \- To Avoid Injury
Do not operate damaged or malfunctioning hoist.
Do
not lift more than rated load.
Do not lift people or loads over people.
Do
not operate with twisted, fouled or damaged
web strap.
Do not use a handle extension.
Do
not operate hoist unless hoist body, web strap and
load block or hook are in a straight line.
Do not operate hoist until load is properly seated
in hook.
Do
not attempt to free wheel web strap with a load
on hoist.
Do not use hoist web
strap for a sling or drag strap
under load.
Do
not operate except with hand power.
Do not remove or obscure the warning decal.
Do not allow web strap and hoist to be dirty -clean
and dry thoroughly. Relubricate hoist.
IA- DANGER 1- To Avoid Electrical Shock
The web strap on this hoist is NOT an insulating
member.
When clean and dry, the strap may have
dielectric properties typical
of nylon or polyester
fibers.
Use an appropriate insulating member in series
with hoist and web strap to achieve proper working
distances
per OSHA Regulation Subpart V, 1926.950
or your company work practices. When handle
swings closer to energized conductors than permis-
sible OSHA safe
working distances or company
practices, use appropriate clothing and rubber gloves
for
rated voltages.

INTRODUCTION
This Lineman's web strap hoist utilizes a friction type
holding brake to provide more precise positioning than is
available with ratchet-and-pawl design hoists. The
nonmetallic webbing and handle provide an extra
measure
of safety for use around energized power lines.
The hoist should not be used as a substitute for approved
insulators when tensioning energized lines. The model
2000A has pawls that are operable with hot sticks. In
addition, the model 2000DA has hot stick rings on all
hooks and the operating handle.

OPERATION
Safety Notes:
1. Be sure hoist is clean and dry before using. This is
important to assure proper brake action in addition to
maintaining the hoist's dielectric qualities.
2. Be sure webbing is wound smoothly on the drum and
is not twisted at any point.
3. Do not side pull; make sure hoist can align itself with
the direction
of loading.
4. Do not wrap the webbing around the
load-use a
proper sling.
5. Raise the load only enough to make the webbing tight
then double check the rigging to see that hooks are
securely seated before continuing the lift.
6. Do not lift people or loads over people.
7. Do not use a damaged or malfunctioning hoist.
8. Do not overload. Any crack in the handle is evidence
of serious overloading.

lifting or Pulling
Place handle pawl in the "raise" position by pulling
straight out on the handle pawl ring and rotating it until
the word "UP" faces the operator (see Fig. 1). Wind the
handwheel until the web is tight. The handle may be
stroked through any convenient angle to lift the load.
Lowering
Place handle pawl in the "lower" position by pulling out
and rotating the handle pawl ring until the letters
"DN"
show (see Fig. 1). Again, the handle may be moved
through any desired angle to lower the load.
Free Wheeling (No load on hoist)
Place handle pawl in the middle position between "UP"
and "DN." Lift and hold the holding pawl clear of the
ratchet teeth (see Fig. 1). The strap may now be pulled
freely from the drum. Excess slack can be quickly
rewound on the drum by turning the handwheel, with
or without the holding pawl raised.

MAINTENANCE
General
Maintenance of the hoist is normally limited to cleaning
and lubrication. Care should be taken
in either of these
procedures to avoid wetting
of the brake with water or
solvents.
Cleaning
Unless the hoist has been disassembled, cleaning of its
mechanism should be limited to wiping with a damp
cloth or a dry, stiff brush,
in order to avoid brake disc
contamination.
If the webbing requires a thorough
cleaning, it should be removed (see below), washed in a
mild detergent and water and thoroughly dried before
using hoist.
lubrication
Relubrication should not be required unless the hoist has
had original lubrication removed during cleaning
of
parts. Lubricate the following points with a very light
coat
of a good multi-purpose grease: (a) square thread on
end
of drum shaft, (b) inside of handle where it turns on
hub, (c) holding pawl pivot bushing, (d)
bottom idler pin.
Relubricate the porous bronze main frame bushings by
applying one or two drops
of clean motor oil, allowing to
soak in, and wiping away any excess.
REPAIR
General
Instructions given here are limited to replacing parts that
are most likely to wear during normal use. Replacement
of any other parts are straight forward removal and
replacement.
Strap Replacement
Unwind strap from drum. Remove bottom yoke by
removing yoke pin and remove idler block. Use a lis"
drive punch to remove pin from the handwheel and
remove handwheel. Withdraw the drum shaft, handle,
and ratchet as a complete unit. Remove old strap from
slot in drum. Insert one end
of the new strap assembly in
the drum slot so that the cut end
of the webbing will
wind
up against the drum. Use the drive punch to open
5
the eye in the strap and reinstall the drum shaft,
handwheel, and pin. Slip idler block over end
of strap
and replace bottom block, being sure retaining rings are
secure.
Brake Disc Replacement
Holding handwheel, remove screw from otherend of drum
shaft. Remove handle cap, thread stop, and handle. Turn
handle hub clockwise to remove.
Replace brake discs andlor ratchet being careful to keep
parts clean and free
of grease or oil. Replace hub and
handle, regreasing
if needed. Replace thread stop so that
hub can back off only enough to release brake. With hub
screwed down tight, the clearance between the thread stop
ear and the hub shoulder should be l/S" to
5/]6". Replace
handle cap and screw.
