Compact Winch
Thank you for purchasing a Winch. This manual covers operation and
maintenance of the winch. All information in this publication is based on the latest
production information available at the time of printing.
General Safety Precautions
A Winch is designed to give safe and dependable service if operated
according to the instructions. Read and understand this manual before installation and
operation of the winch.
Follow these general safety precautions:
˙Confirm that the winch complies with the using conditions.
˙Keep the winch secure strongly and the rope is not wound to be deviated to the drum.
˙Don't use unsuitable pulleys or accessories concerned.
˙Don't use unsuitable rope in construction , strength or having any defects.
˙Pay attention to the grounding , it provides a path of least resistance for electric current
to reduce the risk of shock.
˙Check the winch for smooth operation without load before loading operation.
˙Make sure the wire rope to be wound evenly in the first layer on the drum, rewind it if a
mixed windings in existence.
1.The winch is not to be used to life, support or otherwise transport personnel.
2.A minimum of five(5) wraps of rope around the drum is necessary to support the load
rated.
3.Come-Up takes no responsibility for the subsequent performance of mechanical
components if oil possessing properties other than what Come-Up recommends is
used

II. INSTALLMENT PRECAUTION
2.1 ENVIRONMENT PRECAUTION
WARNING
●The following environmental conditions may result in the possible causes of winch
trouble.
●Low temperature below -10oC, ●In a organic chemistry or
high temperature above 40oC or explosive power conditions.
humidity above 90% conditions.
●In heavy acid or salty conditions ※Cause explosion.
Cause malfunction of spare※
part.
●In the rain or snow ●In a heavy general powder
conditions.
Cause rust or short circuit.※
※Cause malfunction of
performances.
2.2 CONTINUOUS RATING
WARNING
●Never hoist over the rated percentage duty cycle.
The life of the winch is depending on the conditions of the load and working frequency.
In the long time operation, make sure to use the machine within its continuous ratings.
Continuous ratings means the working duty cycle (%ED) is subject to the rated voltage, rated
frequency and a 63% of rated load.
Tb
Percentage duty cycle (%ED)＝------------------ X 100 (%)
Tb + Ts
Tb: total sum of overall loadings operating hours.
Ts: total sum of stopping hours.
Tb+Ts=approximately 1 to 10 min

2.3 MOUNTING
The winch designed to be hanged or mounted on a firm or stable bar or a bracket CRH-0710 (as an
option).
When hanging, do not allow the body or load to be caught by any construction of frame, or other
obstruction.
Be sure to lock the hanger for extra safety.
2.4 PLUG INSERTION
2.4.1 Power core insertion
Insert the power plug into the power receptacle of
the winch, and tighten it by turning the locking ring,
clockwise.
Be sure to lock the cord by a holder. Do not allow
the cords to be caught by wire rope and drum.
The length of power cord is subject to the
distance of 20 meter, for any other case, please
use a power cord by 3.5 mm2to prevent a
considerable voltage drop to be happened.

2.4.2 Grounding
To prevent the risk of electric shock, the power plug must be
plugged into a matching outlet and grounded in good condition.

2.4.3 Switch cord connection
1)Insert the switch plug into the switch receptacle of the
winch and tighten it by turning the locking ring clockwise.
Be sure to hook the cord by a holder.
2)To extend the length of to switch cord EXC-0010 as an option,
please adopt a switch extention cord.
III. WORKING METHODS
3.1 PREPARATION BEFORE WORKING
●Be sure to carefully check all safety and environmental conditions.
●A minimum of five (5) wraps of wire rope wound around the drum is necessary.
A wire rope should be discarded and not be used again if rope shows sign
of excessive wear, too many broken wires, corrosion or other defects.
●Make sure to connect the main power source and grounding.
●It’s not safe to lift loads exceeding the rated load.
●Connect power source at rated voltage.
(It will cause maladjusted working if input voltage
falls out of rated voltage by +/- 10%)
3.2 UP AND DOWN SWITCHING
To lift a load, press ↑button and drum will rotate as shown below operation.
To lower a load, press ↓button and drum will rotate as shown below.
When the button is released , the drum will strop moving.

V. MAINTENANCE AND REPLACEMENT
5.1 WIRE ROPE REPLACEMENT
5.1.1 Swivel hook
●Put a new wire rope through the hole of the round plate of swivel hook.
●Insert a sleeve pin through the thimble of wire rope.
●Insert a pin through the sleeve pin and bent it by a pliers.
5.1.2 Drum
●Let a new wire rope w/clamp through the limit lever and insert it into the
hole of the drum.
●Put a P.T. screw into the hole of the drum and tighten it by a hexagon wrenth.
●Press the ↑button to rotate the drum in the lifting direction.
●A uneven winding of wire rope may cause the load to be swing, thus
damaging the rope and reducing its life.

5.2 OIL LUBRICATION
Gear lubrication is an important component in insuring the
long life of your winch. The type of lubricant will have a great
influence. The gear oil your winch was shipped with is Castrol
Alpha Series, SP-220, a viscosity ( cSt ) is 226.14/19.5 at
40℃
℃℃
℃/100℃
℃℃
℃. Consult your local lubricant distributor on the
selection that best fits your climate and application.
The initial lubricant should be changed after the first 10 hours
of operation. Subsequent changes of 100 cc for CWS-80 and
250 cc for CWS-160/230 should be scheduled every 250 hours
of operation or annually.
5.3 CARBON BRUSH REPLACEMENT
WARNING
●Clean the accumulated powder of carbon brush periodically to ascertain the insulation
resistance up to 1MΩ.
●It is essential to check the carbon brush periodically.
If its length is left less than 7.5 mm resulting from
wearing, it is absolute necessary to replace carbon
brush immediately.
●While replacing, smoothly insert carbon brush into
carbon holder in the first place, then put brush cap
into the hole.
●Before tightening the carbon brush holder, make sure to
position O-ring.
●A set of carbon brush consists 2 piece of carbon brush.
Ascertain to replace 2 pcs of carbon brush on opposite
sides of winch body at the same time.
5.4 BRAKING
●Braking device are composed of a mechanic brake and a electronic generated
brake. The brake distance from the time of braking until stopping completely
should be within 1.5% of rope length to the wound in during 1 minute.
