Manufactured by Motive Power Industry Co., Ltd

PREFACE
This manual provides every service specialist with professional
techniques of maintenance and repairing for G-MAX (ALLORO). It
provides a detailed guide for those who may concern with how to maintain,
repair, reassemble, and change parts of their scooters.
This manual includes 3 kinds of engine displacement:
 G-MAX 50 (ALLORO 50): abbreviated as “M2-50” is 2
stroke engine (2T), 50cc displacement.
 G-MAX 125 (ALLORO 125): abbreviated as “M2-125” is
4 stroke engine (4T), 125cc displacement.
 G-MAX 150 (ALLORO 150): abbreviated as “M2-150” is
4 stroke engine (4T), 150cc displacement.
 G-MAX 200: abbreviated as “M2-200” is 4 stroke engine
(4T), 200cc displacement.
 G-MAX 220: abbreviated as “M2-220” is 4 stroke engine
(4T), 220cc displacement.
 G-MAX 250: abbreviated as “M2-250” is 4 stroke engine
(4T), liquid cooled, 250cc displacement.
At every section, we illustrate each important point by assembling
procedures, explosive diagrams and photographs.
Although we have tried our best to make this manual as perfect as
possible, please kindly inform us if any fault needs to be corrected
in this manual.
Thank you for purchasing our PGO scooters.

2. Items with “*” mark indicate our recommendation to have it done by PGO dealer.

NOTE 1：
For 4T engine, the engine oil shall be changed completely after run-in period 300km or one
month later. This can make sure the engine runs smoothly.
NOTE 2：
The exchange of brake fluid
1. After disassembling of brake main cylinder or caliper, do change the new fluid.
2. Check the fluid level often, Refill if necessary.
3. Change the oil seal of main cylinder and caliper every two years.
4. Change the brake fluid hose every four years.
NOTE 3：Available for M2-250 water-cooled engine only
1. Check the clamping and hoses of radiator system initially 1,000 kilometers and per
10,000 kilometers for anti-leaking proof..
2. Replace the engine coolant every year, or every 10,000 kilometers.
