1 operating , Maintenance &Parts ManualJLC680 JLCS eriesThe use of any hoist presents some risk of personal injuryor property damage. That risk is greatly increased if properinstructions and warnings are not followed. Before using thishoist, each operator should become thoroughly familiar withall warnings, instructions, and recommendations in this manual for future reference and this manual to the hoist to operate the equipment as directed in the manualmay cause you have any questions regarding this product,please call Coffing hoists at (800) in the using the hoist, fill in the information below.

3 Since OSHA states the National Electrical Code appliesto all Electric hoists , installers are required to provide currentoverload protection and grounding on the branch circuit section inkeeping with the code. Check each installation for compliance withthe application, operation and maintenance sections of thesearticles.*Copies of this standard can be obtained from ASME OrderDepartment, 22 Law Drive, PO Box 2300, Fairfield, NJ 07007-2300, , , a damaged, malfunctioning or unusuallyperforming the hoist until you have thoroughly read andunderstood the manufacturer s operating and MaintenanceInstructions or a hoist which has been modified without themanufacturer s approval or without certification that it is inconformity with ANSI/ASME B30 more than rated load for the hoist with twisted, kinked, damaged, or worn the hoist to lift, support.

They areemergency devices your attention to be diverted from operatingthe the hoist to be subjected to sharp contact withother hoists , structures, or objects through or repair the hoist unless qualified to performsuch adjustments or operation of a hoist can create a potentiallyhazardous situation which, if not avoided, could resultin death or serious injury.
7 To avoid such a potentiallyhazardous situation, THE OPERATOR SHALL:Improper operation of a hoist can create a potentiallyhazardous situation which, if not avoided, could resultin minor or moderate injury. To avoid such a potentiallyhazardous situation, THE OPERATOR SHALL:3 Country Club Box 779 Wadesboro, NC 28170 USATEL:(800) 477-5003 FAX:(800) 374-6853 Coffing JLC series Electric Chain hoists are rugged, portablehoists that provide quick, precise lifting. The hoists areconstructed of tough, but lightweight, die cast aluminum alloyhousings. An oil bath transmission, equipped with heat-treated,alloy steel gears and an overload limiting clutch, providessmooth and reliable operation.
8 With a pushbutton station thatfits comfortably in one hand, the operator can safely control thehoist while the other hand is free to guide the load. Theelectrical controls use a low voltage circuit (24V standard,115V optional). Terminal blocks allow for easy voltageconversions on dual-voltage features that ensure the safe operation of Coffing electricchain hoists include a magnetic disc brake that delivers surestopping and secure holding of the load. Adjustable upper andlower limit switches regulate the load travel. As a standard,hooks are supplied with safety latches.
9 For additional safety, a Chain stop is attached to the slack end of the load Electric Chain hoists are designed and tested inaccordance with the American Society of MechanicalEngineers Code , Safety Standard for OverheadHoists. hoists are built in compliance with CSA, file number LR 44484. Made in *The 1HP, 115/230V models (JLC1032-1, JLC2016-1,JLC4008-1) must have a dedicated power circuit rated for atleast 20A, 125V when they are wired for 115V. It is notunusual for these models to draw up to 20 amps at 115 Vwhen lifting at rated capacity depending on the quality of thevoltage :The above data is the nominal motor current at full load.
10 At full load, it is not unusual for the hoist to draw in excess of the values listed when lifting. It is critical to ensurethat the voltage at the reversing contactor does not drop below10% of the nominal voltage while lifting a load. Low voltage willresult in higher amp draw, damage to the hoist, and potentialfire hazards.
