Cleaning And Maintenance - Velleman VTHD09 Mode D'emploi

6. Operation
This tool can be used for drilling, sanding and polishing, as well as engraving, cutting and removing rust
in tight spaces. The tool can be used on most metals, glass, wood and ceramics. For best performance
and results, keep the speed as even as possible without exercising too much pressure. As a guideline,
use the tool at low speed for all large accessories, such as polishing, and at high speed for smaller
accessories, such as those used for engraving. For grinding and engraving, hold the tool as if it were a
pen.
6.1 Useful Hints and Tips
•
The tool will become warm after prolonged use and must be switched off to cool it down.
•
To ensure smooth running, periodically oil the shaft.
•
Do not apply too much radial pressure to the accessory bits while polishing, cleaning, sanding or
grinding. By doing this, you will put strain on the shaft and adversely affect the precision of the tool.
Always work with a sensitive touch so as not to impede the efficiency of the tool.
•
When drilling in metal, always mark the drilling point with a centre punch so that the drill will not
slip.
•
Always ensure that you have maximum contact between the accessory shaft and the collet.
6.2 Start-Up
Never start up the tool if the accessory is in contact with the piece to be worked on. Hold it firmly and
press the on-off switch. The tool will run continuously until the on-off switch is flicked to the off position.
Adjust the speed while the tool is running.
6.3 Speed Adjustment
This tool is equipped with a speed control. The speed switch is located on the rear of the tool. Turn it
slightly too increase or decrease the speed.
6.4 Mounting Accessories
Always remove the plug from the mains prior to assembly. Hold the collet lock button while unscrewing
the collet nut and screw the accessory in place. Hold the collet lock button while you are fastening the
collet nut. Do not operate the collet lock button while the device is still connected with the mains.
6.5 Mounting the Flexible Driver
Remove the housing cap and the collet nut. Partially extract the internal transmission cable from the
flexible driver, insert the cable into the collet and screw the driver onto the tool. Keep the shaft lock
button pressed as you do it.
6.6 Mounting Accessories on the Flexible Driver
All accessories can be mounted onto the flexible driver. Follow the same general procedure for mounting
accessories on the tool.
