2.1 Section of cables not suitable.
2.2 Poor electrical connections.
2.3 Dirty brushes.
2.4 Water leaks in the electrical engine.
2 The capstan runs slowly and
2.5 There is no parallelism between upper deck and below deck.

breaker.
2.7 The engine strains in one or both directions.
2.8 The capstan works only in one direction.
3 The electric engine runs but
3.1 Heavy wear or breakage of teeth of the crown / worm screw.
the shaft does not rotate either
3.2 Breakage of the engine spindle.

4 On installation, it is found
that the shaft and the studs are
4.1 The request referred to the deck thickness was wrong.
short for a correct coupling
with the gearbox.
Possible causes
Capitan T500-T700-T1000-T1500-T1700-T2000-T2500-T3000-T4000
1.1 Check the protection switch and set it in the ON position
1.2 Check the charge status of the battery, check connections
1.3 Check and possibly replace the control box
1.4 Check and possibly replace the control
1.5
Measure the electric motor voltage; if it is OK, check the brushes and clean them. If it does not
work, replace the electric motor
2.1 Increase the cable section
2.2 Check out the connections
2.3 Clean the brushes
2.4 Replace the electrical engine
2.5 Work surfaces and/or add shims to restore parallelism.
2.6 (SERVICE) Uninstall the gearbox and check out its condition. Replace damaged parts after
discovering the causes of the leak. Also, replace gaskets and screws. Check out also the engine
condition, which may have been damaged during the malfunction.
2.7 (SERVICE) Check out appropriately all connections of the power cables.
If they are alright, uninstall the engine (in some cases it is convenient to disassemble also the gearbox).
Check out and possibly replace the brushes.
2.8 Check out on the control box that between B2-C and B3-C contacts there are 12/24V when the
espective buttons are pressed. If this should happen and one of the relays does not work, replace the
control box.
3.1 (SERVICE) Uninstall the capstan and replace the broken parts. Check out carefully that pieces or
splinters of broken parts did not enter into the oil circuit and have ruined other mechanical parts. (*)
3.2 (SERVICE) Replacing of the engine. Care must be taken that the broken part did not remain in the
hole of the worm screw. (*)
(*) Take advantage of this opportunity to replace any other worn parts, especially gaskets, screws, tabs,
seeger, and oil.
4.1 If the key shaft works in the gearbox along all its length, the fixing studs can be adapted. Otherwise,
a longer shaft must be requested.
