Excellent overload durability The Models G 10SR3, G 12SR3 and G 13SR3 provide excellent overload durability thanks to an improved cooling mechanism and a high-power motor. Practical test data: Comparison of torque when the stator coil temperature rise is 200 K...
The graph below shows the relationship between load and temperature rise of stator coil. The temperature rise of the Models G 10SR3, G 12SR3 and G 13SR3 is the lowest among similar models. This means that the resistance to overload usage of the Models G 10SR3, G 12SR3 and G 13SR3 is superior to other models.
7. PRECAUTIONS IN SALES PROMOTION In the interest of promoting the safest and most efficient use of the Models G 10SR3, G 12SR3 and G 13SR3 Disc Grinders by all of our customers, it is very important that at the time of sale, the salesperson carefully ensures that the buyer seriously recognizes the importance of the contents of the Handling Instructions, and fully understands the meaning of the precautions listed on the Name Plate or Caution Plate attached to each tool.
7-3. Precautions on Usage (1) The wheel guard must be aligned in relation to the side handle mounting position. As illustrated in Figs. 4 and 5, the customer should be instructed that the wheel guard mounting angle must be aligned and fixed in accordance with the side handle mounting position so that the operator's hand will not contact the depressed center wheel.
8. PRECAUTIONS IN DISASSEMBLY AND REASSEMBLY The [Bold] numbers in the descriptions below correspond to the numbers in the Parts Lists and exploded assembly diagram for the Models G 10SR3, G 12SR3 and G 13SR3. 8-1. Disassembly (1) Replacement of the armature and the stator Loosen the Tapping Screw (W/Flange) D4 x 16 (Black) [51] to pull out the Tail Cover [49].
8-2. Reassembly Put the parts together in the reverse order of disassembly, with the precautions given below. (1) Generously lubricate the teeth of the Gear [18] and the Pinion [5] with grease. Rub grease onto the teeth with your fingers so that the grease reaches each tooth bottom. Note that the Gear [18] and the Pinion [5] may wear at a faster rate if under-lubricated.

(4) When installing the Stator [11] into the Housing Ass'y [37], insert it while taking care of the placement of the internal wires of the Stator [11] as indicated in Fig. 8. Connect the four internal wires of Stator [11] with the parts indicated in Fig. 8. Connect the internal wires correctly as shown in Fig.
Tail Cover [49]. (7) When replacing the Gear Cover Ass'y [3], lubricate the metal part with mixed oil. Mixed oil: Mixture of Hitachi power tool grease No. 2 (Unilube No. 00) and turbine oil Mixture ratio 1:1 (weight ratio) Volume 0.5 cc...
