Assembly
Add a few drops
of lubricating oil
to the front wheel
column before
inserting the front
wheels.
Insert the left and right wheel suspension into
the frame. Then tighten the set screw with the
hexagonal spanner provided to prevent the
wheel from coming loose.
Do not overtighten the screw. Over-tightening
will restrict the swivelling of the wheel.
Mount the two rear axles in the
mounting holes provided on the frame.
Then put the rear tyres on the axle by
pressing and holding the button on the
wheel. To fix the wheel, stop pressing
the button.
