Q: How to change the heads and accessories of the Ferm OTM1005?

Before any handling: Always turn off the machine and unplug the power cord from the outlet. Place the Ferm OTM1005 on a table with the mounting point (3) facing up. Changing the sanding pad and sanding paper: Loosen the Allen screw (7) with the provided Allen key (5). Mount the sanding pad (9) onto the mounting point (3) and tighten the Allen screw securely. Then mount the sanding paper (10) ensuring that the holes align perfectly with those of the pad. To remove, simply reverse the operation. Changing the saw blade: Loosen the Allen screw (7). Remove the spacer (8). Insert the saw blade (11) onto the mounting point (3). Reattach the spacer (8) and then tighten the Allen screw securely. The same procedure applies for removal in reverse order. Changing the stripping knife: Follow exactly the same procedure as for the saw blade: loosen the screw (7), remove the spacer (8), install the stripping knife (12) onto the mounting point (3), reattach the spacer (8) and tighten the Allen screw. Important points to remember: Only use accessories recommended by Ferm for the OTM1005 model. Ensure that the maximum speed of the accessory is equal to or greater than that of the machine (11,000 to 20,000 rpm). Before each use, inspect the accessories to ensure they are not damaged, bent, or dull. If you change a saw blade or stripping knife, check that the spacer (8) is correctly reattached to ensure safe and balanced operation of the machine. After mounting new accessories, let the machine run without load for a moment to check that it does not vibrate excessively.

Question 1

What should I do if the motor of my Ferm TSM1033 produces sparks?

Accepted Answer

Sparks from the motor indicate a serious electrical problem that requires immediate action. Here are the checks to perform:

Priority Checks

Inspect the power cord and plug – Look for cracks, exposed sections, or damaged insulation. If the cord is damaged, the device cannot be used and must be repaired by a professional.
Check the circuit breaker – A short circuit can blow the fuse. If the fuse is blackened or burnt, this confirms an electrical fault. Do not replace the fuse yourself: contact an authorized repair service.
Stop using it immediately – Sparks generally indicate a short circuit or insulation fault (the TSM1033 uses double insulation Class II, but this may be compromised).

Thermal Protection System

The TSM1033 is equipped with a thermal overload circuit breaker (marked no. 8 in the manual). If the motor overheats during heavy use, this circuit breaker automatically cuts off the power. Wait for complete cooling (at least 30 minutes), then press the reset button. If sparks persist after cooling, there is an underlying electrical problem.

Action to Take

If sparks are visible inside the casing, near the motor, or if you smell burning, do not attempt to restart the device. Unplug it immediately and contact an authorized Ferm repair service center. This type of fault poses a fire risk and requires professional inspection.

Question 2

How to replace the saw blade of the Ferm MSM1039?

Accepted Answer

Before any intervention, disconnect the machine from the power supply.

Accessing the mechanism

Remove screw (20) that secures the return arm to the cover
Remove screw (19) to take off the cover by lifting the blade cover (6)

Removing the old blade

Press the blade lock button (22)
Manually rotate the blade until fully locked
Use a hex key to unscrew bolt (17) clockwise
Remove the flange (18) and the used blade

Installing the new blade

Ensure that the arrow marked on the blade is oriented in the same direction as the arrow marked on the machine
The teeth should point downwards at the front of the saw
Tighten bolt (17) using the lock button (22) to hold the blade in place

Blade specifications

Use a saw blade compatible with the following specifications:

Diameter: 210 mm
Bore: 30 mm
Thickness: 2.8 mm

Reassembly

Replace the blade cover and the return arm, then tighten screws (19) and (20). Manually check that the cover moves freely without obstruction before using the saw.

Question 3

How to switch to the unscrewing mode on the Ferm CDM1112S screwdriver?

Accepted Answer

To set your Ferm CDM1112S screwdriver to unscrewing mode, you need to use the rotation direction switch (mark 9), located above the on/off switch.

Procedure:

Push the switch to the right to activate unscrewing mode
You can place the switch in the central position to lock the switch movement before handling the device

Once the switch is in the unscrewing position (right), you will be able to remove your screws normally. Refer to the manual above to locate mark 9 precisely on your device.

Question 4

How to properly secure the accessories so that they hold firmly?

Accepted Answer

To ensure that the accessory holds firmly on the Ferm CTM1016, it is essential to follow the fixing procedure correctly:

Remove the battery before any handling
Press and hold the axle locking button (reference 3) to immobilize the shaft
Using the provided key, loosen the clamping jaw (reference 1) that can accommodate accessories of 3.2 mm or 2.4 mm
Insert the accessory by pushing it all the way into the chuck - this is crucial to prevent it from coming out
Keep the locking button pressed while tightening
Tighten the jaw firmly with the key until the accessory is securely locked

Key point: Always push the accessory all the way into the collar to minimize imbalances and ensure a stable fixation. If the accessory still comes out, check that you are using the correct jaw capacity (3.2 mm or 2.4 mm) suitable for your accessory.
