Instruction Manual - RIV912
MAINTENANCE
Maintenance operations must be carried out with the tool stopped and disconnected from the pneumatic supply line.
Warnings:
• The tool maintenance instructions must be followed carefully.
• To ensure safety and perfect tool efficiency, it is recommended to use exclusively ORIGINAL spare parts.
CLEANING
It is a good rule to completely clean and grease the tool on a periodic basis (depending on the type and frequency of
use). These operations must be carried out at least once a year.
Shut-off all sources of power to the tool.
The operator must wear and use suitable personal protections before starting to clean the tool.
ORDINARY MAINTENANCE
In order to prevent stoppages and faults of the tool, an ordinary maintenance (including inspections, checks and
operations) must be scheduled to keep the following under systematic control:
• State of lubrication of the tool.
• State of wear of consumable parts.
REFILLING THE HYDRAULIC CIRCUIT WITH OIL
The hydraulic circuit needs to be refilled with oil after a continuous use, and when you notice a reduction in the tool
stroke.
Proceed as follows (see photo above):
• Disconnect the airline from the tool inlet.
• Unscrew cap with relevant washer 27.
• Put the tool in horizontal position and slowly pour in the hydraulic oil (ISO VG 32 type) 84 until the circuit is full.
• Screw cap back on, together with relevant washer 27.
• Connect the tool to compressed air line and start up a couple of idle cycles. Stop pulling the trigger and slowly
loosen screw 8 allowing the surplus oil to come out; screw again screw 8 and the tool is ready to be used.
Wear gloves when managing the oil.
Do not throw the old oil outdoors. Hand it over to an authorized waste disposal center.
Warning!: If you should accidentally spill oil on your skin, wash and rinse thoroughly with soap and water.
