hardware bag (Figure 1).
• Push pins of master link bar
through cable loop and hole in
front end of trolley.
• Push master link cap over pins
and past pin notches.
• Slide clip-on spring over cap and onto pin notches until both
pins are securely locked in place.
2. To prevent the trolley from jamming against the opener during
operation, position trolley 5-15 cm from the stop hole as
shown. Then dispense the chain around the opener sprocket,
(Figure 1). Make sure the sprocket teeth engage the chain.
3. Proceed around to the pulley bracket and forward to the
threaded trolley shaft.
4. Use the second master link to connect the chain to the flat
end of the shaft (Figure 1).
Check to make sure the chain is
not twisted.
5.
Position the sprocket cover over the motor unit sprocket so the
three holes in cover align with the three holes in mounting
plate. Attach with #8x3/8" hex screws provided.
To avoid possible SERIOUS INJURY to fingers from moving
opener:
• ALWAYS keep hand clear of sprocket while operating opener.
• Securely attach sprocket cover BEFORE operating.
