INSTALLATION
17. With the rear hinge frame angle (F) tight against
the rear pit curb angle and flush with the curb
angle (G), weld the rear hinge frame angle (F) to
the rear pit curb angle (G) using a 3/8 in. (9.5
mm) flare bevel skip weld
— each weld being 6 in. (152 mm) long.
Start at each end with a 6 in. (152 mm) long
weld. Space all the other welds out evenly
leaving approximately 6 in. (152 mm) space
between each weld.
NOTE: The illustration on page 12 shows a typical
weld pattern. The weld pattern will vary
slightly depending on size of dock leveler.
IMPORTANT
DO NOT weld continuously along the full length of
the rear hinge frame angle. This can put
unnecessary stress on the leveler components,
causing the leveler to malfunction and shorten the
life span of the affected components.
IMPORTANT
DO NOT connect the dock leveler electrical wiring
and ground connections until all welding has been
completed.
DO NOT ground welding equipment to any
hydraulic or electrical components of the dock
leveler. Always ground welding equipment to the
dock leveler frame, NEVER to the platform.
Failure to follow these instructions may damage the
motor, wiring, and/or control panel.
DO NOT grind or weld if hydraulic fluid or other
flammable liquid is present on the surface to be
ground or welded.
DO NOT grind or weld if uncontained hydraulic
fluid or other flammable liquid is present. Stray
sparks can ignite spills or leaks near the work area.
Always clean up the oil leaks and spills before
proceeding with grinding or welding.
Always keep a fire extinguisher of the proper type
nearby when grinding or welding.
Failure to follow these instructions may result in
serious personal injury or death.
