with the aid of instrument panel:

• Move the left control lever left gently to slew the turntable anticlockwise in order to locate the
counterweight cylinder above the counterweight;
• Press the slewing switch (No.2 in Fig. 5-2) on the control box to align the counterweight cylinder
with its extending position;
• Operate the counterweight cylinder switch (No.1 in Fig. 5-2) on the control box to extend the
counterweight cylinder to the counterweight hole;
• Press the switch No.2 again for slewing the turntable anticlockwise, so that the counterweight
cylinder aligns with the counterweight lifting position;

to the highest position.
