Safety Instructions for Ratchet Hoists
1. KEEP ALL SAFETY DEVICES IN
PLACE and in good working order.
2. LIFTING POWER. This ratchet hoist
is designed to be comfortable for
one person to lift the load using
only hand power. Never use a motor
or an additional mechanical device
with this ratchet hoist to lift the
load.
3. SAFETY HOOKS. Before lifting,
inspect the safety hooks to make
certain they are securely attached,
and verify that the safety catches
are operating correctly.
8. WARNING LABEL. Always make sure
the warning label on the hoist is
legible so that the operator can be
aware of the immediate hazards
of operating the hoist. If the label
becomes damaged, replace it.
7. CRUSHING HAZARD. If the load
should fall, it could cause death or
serious personal injury to anyone
underneath the hoist. Always make
sure the operator and bystanders
never move under the load.
8. OPERATION SPEED. Use a slow
and steady pace when raising or
lowering the load to avoid jerking
or tangling the chains and load.
9. HEAD PROTECTION. Always wear a
hard hat or similar head protection
when using the hoist.
4. METAL FATIGUE. Before using,
inspect the hooks, chains, and hoist
housing to verify that the metal
parts do not have cracks or other
signs of potential failure.
5. DYNAMIC LOADING. Swinging or
jerking the load will cause dynamic
loading that could exceed the
capacities of the hoist, which could
result in the load falling.
10. OPERATIONAL DIFFICULTY. If
the lifting chain seems to require
excessive force to lift the load,
check for the following and resolve
them before continuing:
6. VERTICAL MOVEMENT. The ratchet
hoist is designed to only move the
load straight up and straight down.
Swinging or dragging the load could
cause hoist failure.
7. CHAIN ENTANGLEMENT. Always
make sure the chains are not
twisted around each other before
lifting. Keep body parts, long hair,
and jewelry away from the chains
and hooks to prevent entanglement
during lifting.

OPERATION
To operate the ratchet hoist, do these
steps:
4. Flip the lever on the ratchet handle
to the neutral ("N") position. This
allows the lifting chain to freely move
through the gear block housing by
either pulling on the lifting chain or
rotating the handwheel.
1. Read and follow the safety
precautions included in the front of
the manual, wear protective head
gear, and clear the area around the
lifting operation.
5. Make sure the chains are not tangled,
then attach the lifting hook to the
load.
2. Secure the safety hook on top of the
hoist housing to a structurally sound
overhead beam that is capable of
supporting the load weight.
6. Eliminate the slack in the lifting chain
between the gear block housing and
the load by pulling on the chain.
Make sure that the overhead
connection point conforms to the
required local and state safety and
building codes for the hoist and load
used.
7. Flip the ratchet lever to the "UP"
position, then pull on the ratchet
handle until there is slight tension on
the lifting chain.
Note: The hoist can be mounted a
beam trolley if the capacity of the
trolley system is at least twice the
maximum load capacity of the hoist.
8. Inspect the hoist and load to make
sure that the lifting chain will stay
vertical and will not twist during
the lifting operation, that there
is not a possibility of any type of
entanglement, and that there are no
obstacles in the path of the lift.
3. Position the load directly under the
ratchet hoist.
9. While keeping to the side of the
lifting path, continue to pull on the
ratchet handle with a slow and steady
pace.
Always connect the ratchet hoist
lifting hook to a separate lifting
device attached to the load, such as
straps, chains, or eye bolt. DO NOT
wrap the hoist lifting chain and hook
around the load in any way. If you
do, the dynamic loads could exceed
the capacity of the hoist, causing it
to fail and drop the load. A falling
load could cause death or serious
crushing injuries.
Note: The ratchet mechanism will
suspend the load at the current
position when you release the
ratchet handle.
10. To lower the load, flip the ratchet
lever to the "DOWN" position, then
pull on the ratchet handle with a
slow and steady pace.
11. When the tension between the hoist
and the load is completely released,
detach the hoist hook.

D4065/D4057 Ratchet Hoist Manual
Follow regular maintenance to keep
the hoist in good working condition. To
avoid serious injury from hoist failure,
never attempt to repair a hoist that
malfunctions or becomes damaged. Hoist
repair or service must be done by a
qualified technician only.
Cleaning
To prevent the chains from jamming,
clean away dirt and debris from the
outside of the hoist housing and the
chains.
NOTICE
The hazard of an improper repair job
is that it could cause the hoist to fail
and unexpectedly drop the load, which
could crush or kill people below, or
cause major property damage. For this
reason, we strongly recommend replacing
the hoist if it malfunctions or becomes
damaged.
DO NOT submerge the hoist housing
in liquid of any kind or allow liquid
to enter the brake cover during
cleaning, or the braking mechanism
may fail to work properly.
Chain Lubrication
When the chains are clean and dry, apply
a thin coat of light machine oil to the
links with an oiled shop rag to ensure
smooth movement and prevent corrosion.
To avoid contaminating the friction brake
during maintenance, you must know the
difference between the gear cover and
the brake cover (see Figure 1).
Storage
The Gear Cover will be removed during
routine maintenance. The Brake Cover
should only be removed by a qualified
technician; it encloses the friction
brake and protects it from exposure
to contaminants, such as liquids or
lubrication, that will cause the brake to
fail under load.
Before storing the hoist, clean and
lubricate the chains. Always store the
hoist in a clean, dry, and protected area
to prevent corrosion or damage.
A malfunctioning or damaged hoist
may drop its load and crush or
kill people below, or cause major
property damage. To reduce this risk,
observe all care and maintenance
noted in the manual. If hoist
malfunctions or becomes damaged,
replace it, or have it serviced by a
qualified service technician.

3. Remove the two disc gears from the
Greasing Gears
housing.
Clean and grease the hoist gears every 6
months of normal use, or more frequently
with heavier use.
4. Use mineral spirits, a stiff-bristled
brush, and shop rags to clean the old
grease and grime from the disc and
splined gears.
Items Needed

Wrench or Socket 13mm.................... 2
Mineral Spirits .....................As Needed
Stiff-Bristled Brush .......................... 1
Shop Rags ..........................As Needed
Multi-Purpose Gear Grease......As Needed
Take care not allow the mineral
spirits or lubricant to drip into the
lower ratchet housing and onto the
braking mechanism.
To grease the hoist gears:
5. When the parts are dry, apply a
medium coat of multi-purpose gear
grease to the gear teeth.
1. Lay the hoist housing on a flat
working surface with the brake cover
facing down.
6. Re-assemble the components in the
revers order that you disassembled
them.
2. Remove the three lock nuts that
secure the gear cover, then remove
the cover (see Figure 2).
7. Test the lifting capabilities of
the hoist with no load, then, if
successful, with the rated maximum
load for your hoist.
