C2 Safety lever C4 Spring-loaded pin
Use the Type «SAK» safety clutch to protect operator from accidental
start-up.
1. Insert casing coupler B8 into tool connection.
2. Depress spring-loaded pin B7 and completely insert casing
coupler B8.
3. Spring-loaded pin B7 must click audibly into place in retention
hole C1. Ensure that spring-loaded pin B7 has locked firmly into
place. If necessary, move/rotate casing coupler B8 until spring-
loaded pin B7 clicks into place.
3.4 Connect toolholders
(Fig. C)
The connection of toolholders corresponds to the procedure descri-
bed in Item 3.3.
Note: Toolholders TALM, TAM, FSM and SAM can be rotated on the
casing coupler B8 for easier handling.
3.5 Start-up with SAK safety clutch
(Fig. D)
Attention: The powerfull machine develops a heavy torque when swit-
ched-on. Thus secure yourself in a rigid position and hold on to the
handpiece.
Only with machine in OFF position! A1
1 Depress locking pin C3.
2 Completely depress safety lever C2. If necessary, move to starting
position by turning the working spindle D1 and repeatedly depres-
sing safety lever C2.
• Switch on drive motor A1.
• Switch off by releasing lever C2. Torque transmission to the
toolholder is interrupted. Locking pin C3 protects from automatic
start-up.
• Switch machine off in order to return safety lever C2 to starting
position!
4.0 Accessories
Important informatory sign. Toolholder maintenance: General
• Clean off grinding dust daily.
• Do not immerse in liquid.
• Bearings are greased for life.
• Change gear grease every 12 months (your
tre can perform this work quickly and efficiently.)
• See respective spare parts list for wear parts.
Change of tools / abrasives: General
• Unplug power supply before each tool change.
• Clean clamp fitting before mounting.
• Ensure flawless runout and only use low-vibration tools. It is es-
sential that you take note of the permissible speed in this context.
4.1 TALM - Angle grinding head with water feed
Attention: Electric current protection
If hand tools with central waterfeed are used one must install a ISK10 -in-
sulater coupling between flex. Shaft and motor mount A2. The electric
unit can only be operated in a low voltage -42V- mode, with a cut-out-
transformer.
