CAUTION
Ensure that the carbon brush toe is inserted in the external tube of the brush contact part.
(You can insert either of the two toes supplied). Take care, because a mistake in this operation could deform the toe and
prematurely damage the motor.
DO NOT attempt to dismount more parts than are necessary to replace the contact carbon.
5.4. Motor and armature
Ensure that every 100 hours you remove any carbon dust on the motor and on the brush housing.
The motor armature must remain permanently clean and its surface must be uniform (light bronze in colour).
5.5. Reservoir oil level
Ensure that the oil level is always above the black line on the viewer. Do not fill the reservoir with noncompatible
oil or brake fluid. Oil type: VESTA HLP-15 manufactured by VERKOL or similar. Remove the reservoir cap and add oil
to the level marked. The oil must be filtered first. If necessary, any quantities you may require could be supplied
from our factory.
5.6. STORAGE
In order to prevent damage to the tools, caused by impact, dust etc, we would recommend storing the tools in their
transport and storage cases.
5.7. OIL LEVEL
Periodically and particularly after extended use, it is advisable to check the oil reservoir level and add oil when
required.
5.7.1. Refilling the oil reservoir.
• This operation should only be performed by authorised technicians.
• Important: the hydraulic oil must be filtered, have an ISO grade viscosity of 15, a viscosity index of 100
and conform to the AFNOR NFE 48603-HM and ISO 6743/4 L-HM standards.
5.8. Punch, Die and Stud lubrication
For extended punch and die duration and to use less force, it is advisable to lubricate the punch and die cutting
edges with a little oil. This will also facilitate the detachment of the knockout.
5.9. WARNINGS
Particular care should be paid to ensure that the punch is screwed right into the stud, in order to prevent the stud
or thread from breaking, and also to prevent the tool from reaching the end of its travel limit without having cut right
through the sheet.
To operate the tool correctly, the WORKING POSITION must be the natural one, that is with the handle pointing
downwards.
