READ THIS BEFORE OPERATING UNIT
INSTA LLATION:
Mount on clean. flat surface. Bolt down with 6-1 /2" bolls. For ease of service,
we do not recommend welding frame to surface.
To wire unit to power, connect one battery cable from positive post on winch
control box to positive side of power source. Connect the other battery cable
to the negative side. Negative cable may not be necessary when winch and
battery are attached to common ground. Use #4 battery cable for operations
with 1 o feet or less between winch and battery. Use #2 for more than 1 O feet.
Before the unit is wall mounted, or mounted upside down, remove P/N 286260
Oil Plug Valve and exchange with PIN 286250 Oil Plug located below the
control box on the worm gear housing cover.
CABLE CONNECTION AND CABLE SAFETY:
Maintain at least 4 wraps of cable on the drum at the maximum reach. The
drum cable clamp 1s not designed to hold load. Inspect the winch, sheaves
and cable frequently. Especially watch for frayed cable, loose parts and worn
components which may be hazardous. Use the correct size and length ot
cable for the Job. We recommend use of 1 /4" cable for most jobs up to 2500 lb.
double hne. Always provide a 5 to 1 safety factor.
The cable tensioner is designed to prevent the cable from riding over the
drum flanges and to maintain a constant pressure against the cable to keep it
from binding.
When rnstalling the cable. cable should be placed between the drum and
the tensioner, bringing cable around drum to hole in flange. Push cable through
hole and secure screws so that they do not extend through the drum flange
and interfere with cable tensioner. Be sure cable is wrapped as evenly as
possible on drum.
For best results, use only enough cable to meet specific Job requirements.
Worn cable is dangerous. Replace cable that has become frayed, broken,
kmk:ed or abraded
OPERATION:
CAUTION: DO NOT REVERSE ROTATION INSTANTLY.
Winch drum should be allowed to coast to complete stop before
reversing rotation.
These units are designed for intermittent use. Mfg recommends a 25% duty
cycle That 1s. for good motor hie, usage of 15 minutes out of one hour is
preferable
To prevent shock: loading. slowly remove slack from cable before lull load 1s
moved
For no load unwinding of cable. tum drum rn either direction. by hand. to free
ciutch dogs bebre pulling on clutch handle
Do not attempt to disengage the clutch with a load on the winch.
Remote switch provides forward and reverse control. Lifting power is the
same 1n either direction For additional safety. a power dtsconnect may be
installed to provide means of cutting power in place of using the battery cable
to disconnect
Do not hamme r on motor as it may break the magnets in motor.
MY-TE WINCH-HOISTS ARE DESIGNED
FOR MATERIAL HANDLING USAGE.
MAINTENANCE:
Check all sheaves, rollers and areas of friction. Be sure they tum freely.
Misalignment of cable. dragging sheaves, or rollers will consume a great amount
of power.
If the unit is installed outside, be sure to provide a cover to protect motor and
controls from the weather. When the unit 1s in operation be sure cover is
completely removed.
Periodic inspection of switch and battery cable should be made to detect
any damage or cuts which would require replacement.
The gearbox oil is shared between the spur and worm gear housings. The
factory-installed oil is a Shell product; Omala 68. It is an EP type industrial
gear oil, ISO Grade 68. If this is not available, an SAE 20 weight, non-detergent
motor oil is acceptable. Standard capacity is 18 ounces.
TROUBLE SHOOTING AND REMEDIES:
If the unit runs free m one direction, but binds in the other direction, loosen
lock collar on outboard drum shaft bearing. Run winch in free direction a couple
of turns. Take hold of drum and hold in the direction of the outboard bearing
and while holding, lighten bearing lock collar. This re-setting eliminates friction
between worm and worm gear due to excessive end play of main shaft.
If the unit runs, but does not pull capacity, be sure battery leads are clean
and tight. Check for good clean ground connection at winch. Check battery for
charge. Without load. run motor in both directions. If motor pulls hard in one
direction, ctieck for and adJust main shaft end play as in previous instruction.
If the unit does not run but solenoids click, check all connections. Be sure
there is full power from battery to winch. This condition may indicate a faulty
motor.
If the solenoids do not click, be sure battery cable connections are intac:
Open control box and remove switch wires. Manually connect a test wire from
any solenoid small top post to positive battery connection. If unit operates.
problem is in switch. If unit does not run, this could be a faulty motor
To run motor without wiring connected, remove the two leads that come
from the electncal panel and are connected to the motor. Disconnect ground
and positive leads from unit. Connect positive battery cable to one motor post,
and the negative to the other motor post. (Caution: This will cause an arc.) Be
careful that the power leads do not touch the motor housing. If motor runs
okay, the problem would be in the panel or switch. If possible to check
amperage. the normal draw would be10 amps.
If motor shows high amperage draw (but not a complete short), remove spur
gear housing cover. Remove idler gear and try motor again to determine
whether drag is in motor or winch. If drag 1s 1n the winch, check for excess end
play or bent main shaft II drag 1s in motor. the usual checks for shorts should
be made. If no shorts are found, check motor bearing for bind.
If the unit does not operate properly after the above remedies. contact a
qualified electncian or the factory.
