9. PRECAUTIONS IN DISASSEMBLY AND REASSEMBLY
The [Bold] numbers in the descriptions below correspond to the numbers in the Parts List and the exploded
assembly diagram for G 13YD, and the <Bold> numbers to those in the Parts List and the exploded assembly
diagram for G 13V.
9-1. Precautions in Maintenance and Repair
(1) Without fail, remove the plug from the power outlet to prevent accidental starting of the tool.
(2) Remove the depressed-center wheel to prevent it from being damaged.
(3) Do not strike the main body of the tool with a hammer or similar tool. The electronic control circuit built into the
Controller Set [45] <45> can be damaged by the impact of a hammer or similar tool. Under no circumstances
should such tools be used when the controller set is assembled in the main body.
(4) Do not attempt to remove or replace internal parts of the Controller Set [45] <45>. The controller set is the
very "brain" of the tool, and should never be disassembled.
(5) When reassembling the tool, ensure without fail that the Magnet [38] <38> is properly installed. Also, note that
the magnet is left-hand threaded, and must be turned counterclockwise to mount it on the Armature [9] <9>.
On reassembly, tighten the magnet onto the armature with a rated torque of 1.27 0.29 N•m (13 3 kgf•cm,
0.9 0.2 ft-lb).
(NOTE) When disassembled, never place the Magnet [38] <38> in the vicinity of metal particles or shavings.
Should such metal particles adhere to the magnet, they could cause malfunction of the control circuit and/or
serious damage to the commutator-side ball bearing of the armature.
