Every year, workers on suspended scaffolds are injured, become disabled, or are killed
because of carelessness or because they did not understand how to correctly operate the
equipment. Do not become one of them. Know how to use this equipment and prevent
accidents. NEVER operate equipment that you do not understand. You may cause
accidents, resulting in injury or death to you or people around you.
This instruction manual is not all inclusive. It is impossible to anticipate every possible way this equipment
may be used, and all possible hazardous situations. It is very important that you determine for yourself
whether the equipment is safe. You must understand the operating characteristics of this hoist. You must
understand how the hoist will operate in your application. You must be certain not to put yourself or others
in danger, or cause damage to property or other persons. Call your hoist supplier if you have any questions
concerning this equipment.
1. Read and understand this manual  using this equipment.
2. Setup and use must comply with Spider®instructions and local codes.
3. Use the Troubleshooting Guide in this manual to solve problems that may develop with the hoist.
Repairs must only be made by people trained and authorized to do so.  maintain or repair the
equipment while the unit is suspended (above ground level).

4. Be careful when operating the hoist in freezing temperatures. Water or moisture may enter the hoist’s overspeed
brake or traction assembly. See “Cautions for Cold Weather Operation” on Page 21.
5. Be careful when operating the hoist in high winds. Consider stopping work or adding stabilization at
wind speeds of 25 mph or more when working on a 2-line suspended platform. When working on a
single line platform, stabilization should be used in winds above 20 mph. Avoid carrying large panels of
material which can act like a sail in high winds.
6. Do NOT remove any parts from the hoist without replacing them. Do NOT change or substitute any

 The voltage loss for 100 ft (30.48 m) of 10/3 electrical cable is 2 volts for each hoist used.
 If startup is sluggish, determine the voltage at the motors when running. UP is between
177-229 VAC.
 If the voltage is lower than 177 VAC when running:
Increase voltage with a transformer at the power source when voltage is low,
Use larger gauge or separate electrical cables for each hoist to improve voltage supply.
Do not start both hoists at the same time to ensure better hoist performance.
Always maintain a level platform.
Follow the manufacturer’s instructions for
platform assembly.
The hoist can be lifted into position by hand or
under power.
Attach the hoist stirrup bar to the platform
stirrup.
Connect the hoist to the power supply. Spider®
electric hoists have a twist lock plug.
The power indicator light will come on when
the hoist receives power.
