Maintenance
On a regular basis:
• check that all connections and mountings are secure.
• check pipes and cables for any signs of wear or damage.
• check pipes and joints for any leaks.
Pump maintenance
The pump contains no user-serviceable parts. Contact your dealer for more information.
Motor maintenance
The motor contains no user-serviceable parts.
However, for the purposes of replacement or coupling examination, the motor can be
removed from the pump head without fluid loss or air ingress into the hydraulic system:
1. Undo the two M6 socket head cap screws (5 mm AF allen key) and remove the motor,
coupling, and water seal ‘O’ ring.
2. If the coupling is worn or damaged it will need to be replaced. Lubricate the slots with a
small quantity of good quality grease.
3. If any hydraulic fluid is found in the coupling area, the pump shaft seal will need to be
replaced. Refer to your dealer for instructions.
4. Reassemble by replacing the ‘O’ ring. Engage the coupling between the motor and pump
shafts, ensuring that the motor locates correctly in the pump spigot. Using a low-strength
thread-locking compound, replace and tighten the two M6 socket head cap screws, using
13.5 Nm torque.
Note:
Keep all parts clean during dismantling and reassembly.
