Cover the weep hole on the top of the DRAIN

DRAIN port DH500 gland slowly. A wrench for
the DRAIN port gland is supplied in the PG7202

DRIVE BELT REPLACEMENT
Periodic replacement of the drive system belts may be necessary to retain maximum
performance of the rotational engagement system. Due to specific material properties of the
drive belts, it is important that only genuine
DHI
replacement parts be used.
A set of spare drive belts is included in the accessories delivered with the PG7000
Platform.
To remove the drive belts:
Using a 2.5 mm Allen tool, remove the three screws on the outer diameter of the
pulley plate.
Do not remove the screws on the inner diameter.
The pulley plate is
located directly around the mounting post.
Remove the two drive belts and replace them with the new ones.
Realign the notched pulley with the pins on the drive motor.
Replace the pulley plate and three screws.
Engage the drive system to ensure proper operation.
