Quick Release Lever
Operation
CAUTION: Never fasten the Sun Bicycles Tug-a-Bug to
the seat post by tightening the quick release lever as
though it were a wing nut. Simply rotating the lever in a
circular motion until tight will not fasten the hitch to the
seat post. Detachment of the Tug-a-Bug as a result of
improper quick release installation can result in serious
bodily injury.
NOTES
If the quick release lever can be easily pushed to the
CLOSED position, this means the clamping strength is
insufficient. Return the quick release lever to the position
perpendicular to the bicycle frame. And again turn the
adjusting nut clockwise to increase the clamping
strength. Push the quick release lever back to the
CLOSED position.
If the clamping strength is adjusted too strong and the
quick release lever cannot be pushed to the CLOSED
position, turn the adjusting nut in a counter-clockwise
direction to reduce the clamping strength. When doing
this, do not fully release the adjuster nut.
Tur n i t 1 / 8 of a r evo l u t i o n , and t h e n tr y to p u s h t h e lever
to CLOSED, to set the maximum clamping strength with
which you can push the quick release lever to the
CLOSED position.
POSITIONING OF THE QUICK RELEASE LEVER
For safety, the quick release lever should be pointing
backwards, running along the trailer hitch arm when in
the CLOSED position.
Adjustment and pre ride check:
Prior to each use, the following must checked to
insure a safe ride.
1) Check that the hitch is in the lowest position on
the seat post and the plastic shim is properly
installed.
2) Check to insure the quick release hitch pin is
properly installed and tight, and that the safety pin
is installed.
3) Check that the trailers seat is tight and level.
Adjust the saddle height so that the rider’s leg is
slightly bent when the pedal is in the lowest posi-
tion.
4) Check the trailers handlebar. Make sure it is
tight and does not slip under pressure. Adjust the
position so the rider can rest their hands comfort-
ably with a slight bend in their elbow while seated
in an upright position.
5) Check the tire pressure, which should be 35-to-
40psi.
Inspect all bolts, nuts, and the frame and hitch of
your trailer for wear. If any wear exists contact your
local Sun Bicycles Tug-A-Bug dealer for replace-
ment parts and do not use your trailer until those
parts have been replaced. Serious injury or death
could occur to either rider in the event of a failure.
Protective Apparel:
The rider of the bicycle and the rider of the trailer
must always wear a helmet. Unlike operating a
bicycle without a trailer, there is more chance for a
loss of control leading to an accident. It is recom-
mended that elbow and knee pads also be worn for
protection.
