1.3 Make sure there is no sundry on column tracking surface before lifting, or the slide blocks may
be damaged;
1.4 Load type of electric motor is S2, with 15 minutes working time;
1.5 Maxima Heavy Duty Column Lift is equipped with double safety system of mechanical lock and
hydraulic check valve. Before working under elevated vehicle, please make sure there is no
abnormality with all connections;

1.11 Lower all columns onto ground after operation;
1.12 During repair works, the horizontal strength on vehicle should not exceed 20% of vehicle’s
dead weight;
1.13 Do not press UP/DOWN frequently for short lifting/descending, except in SINGLE mode;
1.14 Operate the lift strictly according to instructions and warning in Fig. 1;
