Internal gear case because they are adhesive-coated screws.
Always use brand-new M4x12 pan head screws.
*Tighten four M4x12 pan head screws to the recommended
torque of 0.88 - 1.8 N.m (9.0 - 18 kgf.cm).
Note: Remember to use a criss-cross tightening pattern.
[3] Lubrication of Hammer Section
Before assembling, apply Makita grease N. No.2 to the Fig. 13
following parts (Fig. 13);
(1) Top of the Spindle where Anvil contacts ........ 0.5 g (2)
(2) Steel ball 5.6 (2 pcs) ....................................... 0.5 g
