not avoided, WILL result in death or serious injury.
Indicates a potentially hazardous situation which, if
not avoided, COULD result in death or serious injury.
Indicates a potentially hazardous situation which, if
not avoided, MAY result in minor or moderate injury.
It may also be used to alert against unsafe practices.

Safety Instructions for Electric Hoists
8. ONLY USE RECOMMENDED
ACCESSORIES. Using improper
accessories may cause injury.
1. READ ENTIRE MANUAL BEFORE
USING. Trained users have a lower
risk of injury than untrained users.
9. CHECK FOR DAMAGED PARTS
BEFORE USING HOIST. Check for
broken parts, loose bolts, frayed
cable, cracked or worn components
and any other conditions that may
affect operation. Repair or replace
damaged parts.
2. NEVER ALLOW UNQUALIFIED
PERSONNEL TO SERVICE HOIST.
Servicing hoist incorrectly may
cause failure under load.
3. DO NOT LIFT MORE THAN THE
MAXIMUM CAPACITY. Be aware
that the load weight, harnesses,
and load bearing equipment
all contribute to the total load
weight. Overloading the hoist may
cause the load to fall.
10. ALWAYS DISCONNECT FROM
POWER SOURCE BEFORE
ADJUSTING. Make sure the switch
is in the OFF position and the hoist
is unplugged before servicing or
adjusting.
4. NEVER LIFT LOADS WHEN
TIRED, OR UNDER THE INFLUENCE
OF DRUGS OR ALCOHOL. Be
mentally alert at all times when
lifting heavy loads.
11. NEVER ALLOW LOADS TO SWING.
Unsteady loads may become
unbalanced and fall. Swinging
motions cause wear on components
and may cause them to break.
5. AUTHORIZED USERS ONLY.
Only allow trained and properly
supervised personnel to operate.
Make sure operation instructions
given while training others are
safe and clearly understood.
12. USE CORRECT HARNESSES. Never
use oversized or multiple harnesses
in the hook. Use harnesses that are
rated for the load being lifted.
13. DO NOT EXPOSE TO WATER.
Moisture increases the risk of
electrical shock.
6. NEVER LEAVE A SUSPENDED LOAD
UNATTENDED. Lower load to the
ground and unhook all loads and
harnesses before walking away.
14. ENTANGLEMENT HAZARD. Do
not hold the hoist or lifting cable
during operation. Clothing and
body parts may get entangled.
7. NEVER SUSPEND THE LOAD OVER
OR NEAR A PERSON. Loads may
fall at any given time due to
overloading, improper loading
procedures, or failure of a
component. Also, cables can whip
with great force if they break
under load.
15. NEVER USE HOIST FOR
HORIZONTAL PULLING OR
DRAGGING. This hoist is only
designed for vertical loads.

Service at (360) 734-3482 for advice.
Save the containers and all packing
materials for possible inspection by the
carrier or its agent. Otherwise, filing a
freight claim can be difficult.
Working Clearances
Consider existing and anticipated needs,
dimensions of your lifting platform, size
of material to be lifted, and whether
you need the hoist to be mobile or in a
stationary location when establishing an
installation site for your electric hoist.
When you are completely satisfied with
the condition of the shipment, you should
inventory the contents.

Model D4070/D4077 Electric Hoist
Mounting
The Model D4070/D4077 electric hoist
comes pre-assembled and only needs to
be mounted to prepare for operation.
There are many mounting options for
your hoist. It may be mounted on a metal
tubing or on a rotating pillar (Figure 3).
Above all, choose a mounting option that
is safe and will withstand the maximum
rated load of the hoist.
Figure 4. Securing mounting bracket
(pole not shown for clarity).
3. Firmly tighten the hex bolts, and
check to make sure the hoist does not
swing or move after mounting.
Lifting Equipment
When attaching lifting equipment to
the electric hoist:
•
DO NOT attach multiple chains or
harnesses directly to the hook. Only
one point of contact should be used
on the hook and shackle to lessen
the chance of the load falling and to
allow proper load alignment. Use a
multiple chain sling similar to the one
shown in Figure 5.
Figure 3. Hoist mounted on rotating
pillar.
Also, make sure that the selected
location is in a well lighted environment,
the control switch will be within reach,
and that the hoist will not be exposed to
rain or moisture.

multiple chains.
•
DO NOT attach oversized items
or harnesses directly to the hoist.
Oversized lifting equipment creates
multiple points of contact and will
not fit properly on the hoist hook,
resulting in uneven and dangerous
lifting loads.
Note: We strongly recommend using
medium strength thread locking
compound on the hex bolts when
securing the hoist.

distance.
The Model D4070/D4077 electric hoist
has a safety stop microswitch that will
automatically shut OFF the motor before
the lift or pulley hook can be retracted
into the housing.
4. Use the control handle to fully retract
the cable.
– If the motor shuts OFF when the
cable stop compresses the spacing
rack (Figure 7), the safety stop
microswitch feature is working
correctly and the test run is
complete.
If the hook is allowed to retract into
the housing, the hoist will continue to
pull the cable until the cable or cable
hardware breaks, causing the load to
drop.
– If the motor does not shut OFF
when the cable stop compresses the
spacing rack, immediately release
the UP/DOWN switch. This safety
feature must work properly before
proceeding with regular operations.
Call Tech Support at (360) 734-3482
for assistance.
A dropped load can kill or
seriously injure people on the
ground. NEVER allow anyone to
walk underneath a hoisted load,
and ALWAYS verify the integrity
of how the lifting equipment is
attached to the hoist to prevent
accidentally dropping a load.
Spacing Rack
After mounting the hoist, the safety stop
microswitch must be tested before lifting
any loads.
To test the operation of the hoist:

grounded 110V outlet.
2. Grab the lift hook and pull it away
from the hoist while using the control
handle to lower the hoist cable a few
feet by pressing the switch downward
(see Figure 6).
Like all tools there is potential
danger when operating this tool.
Accidents can be caused by
lack of familiarity or failure to
pay attention. If normal safety
precautions are overlooked or
ignored, serious personal injury
may occur.

OPERATIONS
To use the electric hoist:
4. Securely attach the item being lifted
by using the lift hook (for single
cable use) or the pulley lift hook (for
double cable use).
1. Plug the electric hoist into a
grounded 110V outlet.
2. Grab the lift hook and pull it away
from the hoist while using the control
switch to lower the hoist cable by
pressing the switch downward.
Never wrap the cable around the
item being lifted and hook it onto
the cable itself. Damage to the
object and fraying of the cable can
result.
Never fully unwind the cable from
the electric hoist. Always leave at
least 3 turns of cable on the hoist
spool to prevent the cable from
detaching.
5. Check that all bystanders are clear
and that the item has a clear path of
movement.
6. Use the control switch to retract the
cable. Watch the cable as it winds
up on the hoist spool. To prevent
damage to the hoist cable, make sure
that the cable is wound evenly, as
shown in Figure 9.
3. Verify the weight of the item to be
hoisted. Review the Specifications on
Page 3 to see if the operation can be
completed with a single or doubled-
back cable, as shown in Figure 8.

complete, because every work
environment is different. Always
consider safety first and use common
sense. Failure to use this tool with
caution and respect could result in
serious personal injury.

MAINTENANCE
General
Lubrication
Check mounting hardware daily before
use for cracks, unsafe wear, deformation,
or warping. If damaged or worn, replace
it. DO NOT attempt to fix it or continue
using it!
Lubricate the hoist cable with a light
oil to inhibit rust and reduce friction,
depending on frequency of use and
environment. If the cable becomes wet
during use, dry and lightly oil it before
retracting back onto the spool.
Check that the microswitch is functioning
daily before use. Check daily for loose
pins, rings, screws, wires and safety
latches. Tighten or replace any loose
items. Check daily for damage or fraying
along the length of the hoist lifting cable.
Damaged or loose parts may cause the
load to fall, which may result in death or
serious injury!
Never leave a load or hoisting equipment
on the hoist when not in use. This may
cause excessive strain on the hoist and
cable and may shorten their usable life.
Always DISCONNECT POWER before
servicing, adjusting, or doing
maintenance to reduce the risk of
accidental injury or electrocution.
If the hoist becomes dirty, wipe it down
with a damp soft cloth and thoroughly
dry all surfaces. DO NOT use solvents,
chemicals, or other corrosive materials to
clean the hoist.
