INTRODUCTION

The Minibike -PB-G02 is designed and built for use on a paved closed circuit
track. The track should be clean and without obstacles of any kind. Qualified
adults and younger persons can drive the minibike. Children can drive the
minibike only under the supervision of a responsible adult person. The
minibike is constructed especially for racing competitions on special racing tracks.
The minibike uses a single-cylinder two-stroke, Gasoline combustion engine, and
has an air filter and exhaust silencer. Transfer of power to the rear wheel is through
a drive chain. The overall drive ratio to the rear wheel can be changed by the
replacement of chain sprockets. The front and rear wheel is equipped with disk
brakes. The rear brake is controlled with the left fever and the front brake is
controlled with the right lever on the handlebars.

UNPACKING AND SETTING UP BEFORE RIDING

The minibike is delivered in a cardboard carton and packed with folded handlebars
and brake levers. After unpacking, set up the handlebars into the positi o n, t ha t su it s th e
best for driving. The maximum pulled brake lever position should not touch on the
handlebar grip. After setting up, tighten the handlebar nuts 1, brake lever bolts 2, and
the throttle assy. Bolts. See, Fig. 1. The level of foot rest's can be regulated by
loosening the bolt M5 (914.003.01) on the handle of the foot rest (139.001.01). The
foot rest can be moved to the front or back position. It is recommended to try and check
the position of handlebars and foot rest's individually. While tightening the bolts and
nuts, do not use an excessive force as to not damage the threads, or distort the tubes and
other parts. Verify the smooth and perfect function of the Bowden cables to throttle and
both brakes. Fill the fuel tank with fuel. (Gas-oil mix) Failure to use the proper oil mix
ratio will result in Engine damage for which you will be responsi bl e .
