GROOVER Tech Tips

4/20/2017

Tool is not picking up debris or blowing smoke

Check that the blade is not on backwards.

Blade recommendations:

Use the tungsten carbide tipped blade for linoleum and PVC flooring and the diamond cutting blade for anti-slip floors such as those that contain sand or quartz.

HOTWIND Tips

4/19/2017

The HOTWIND must be supplied with cool clean air or used with a filter

In particularly dusty environments or in environments where the impurities are very small, the filter should be covered with stocking material and checked from time to time to ensure it is not clogged. Impurities at the shaft bearings will cause noise and eventually prevent the HOTWIND turbine from turning at start-up.

SARNAMATIC Tech Tips

SARNAMATIC 661

Error 6
Occurs if the nozzle is in the welding position at power-up
Also occurs if the power to the SARNAMATIC cuts out and comes back on while the tool is in use. Power will drop if there is a poor connection in the cord or plug, and due to overload or contaminated fuel when using a generator.

SARNAMATIC 641MC

An error is displayed while the tool is cooling down
Answer: This is not a problem. Errors that come up while the SARNAMATIC is cooling down can be ignored.
Error 7
Occurs if the nozzle is in the welding position at power-up
Also occurs if the power to the SARNAMATIC cuts out and comes back on while the tool is in use. Power will drop if there is a poor connection in the cord or plug, and due to overload or contaminated fuel when using a generator.
Error 8
Occurs if the heat is not turned off at power-up
Also occurs if the power to the SARNAMATIC cuts out and comes back on while the tool is in use. Power will drop if there is a poor connection in the cord or plug, and due to overload or contaminated fuel when using a generator.

TRIAC Tips

4/17/2017

Carry the TRIAC by the handle, not by the cord.

If the TRIAC is often carried or pulled by the cord, the cord will eventually break at the handle. If the cord breaks when the tool is hot, the element and mica tube may be damaged.

If the filter at the back of the handle is plugged, air cannot flow through the tool.

This may appear to be a loss of heat, but it is actually a loss of air. If the tool is operated for a long time this way, the element may burn out. Periodically check that the filter at the rear of the handle is clean, and remove any blockage with a soft brush.

How to Change a TRIAC Hand Tool Element

4/16/2017

If tool is on, turn down heat and allow to cool fully
Ensure the TRIAC is unplugged

Unscrew the four screws of the heater tube with a flat screw driver or a T20 torx bit

TWINNY T Tech Tips

Symptom: Error 100 after turning the heat on

Check that the blower is switched on.

UNIFLOOR Tech Tips

4/14/2017

Symptom: Bad welds or low air volume

Check that the air intake at the blower handle is clear of dust and debris. Clean it with a soft brush to remove any blockage.
Check the air slide at the air intake. Turn it clockwise for more heat or counter-clockwise for more air volume.

UNIROOF Tech Tips

Symptom: Bad welds or low air volume

Check that the air intake at the blower handle is clear of dust and debris. Clean it with a soft brush to remove any blockage.

UNIROOF S/E: Check the air slide at the air intake. Turn it clockwise for more heat or counter-clockwise for more air volume.

VARIANT T1 Tech Tips

4/11/2017

Machine is not running straight

Refer to page 35 of the operating manual and follow the directions given under "Hot-air welding machine moves away from the weld". Adjusting the fine track adjustment lever clockwise adjusts the tracking to the right, and counter-clockwise adjusts it to the left. A test weld must be completed to verify that the tracking is adjusted properly, running the machine without material will not test this properly.

How to Change a VARIMAT Element

If tool is on, turn down heat and allow to cool fully
Ensure the VARIMAT is unplugged
Tip the Electron nozzle up and place in locked position
Unscrew the four screws of the nozzle with a flat screw driver or a T20 torx bit

Carefully slide the heater tube, mica tube, and gasket off leaving the element attached to the tool; set removed items aside
Inspect the mica tube, if it is flaking or curling replace it
