MAINTENANCE
9.6 REPLACEMENT OF OIL SEAL
When Oil Seals (Water Seals) are worn out, water would be leaked from the small
hole on the Fixing Ring.
If you find the water leakage, bring your machine to your nearest Shibuya’s
authorized dealer to have the Oil Seal replaced.
Small hole on the Fixing Ring
9.7 REPLACEMENT OF O-RING
When O-Ring inside Swivel Ring is worn out, water would be leaked from the Swivel Ring.
We recommend replace O-Ring with new one, when Oil Seal is changed.
9.8 REPLACEMENT OF SEAL RING
There is a Seal Ring between Spindle and Oil Seal. The Seal Ring is not visible from outside. However, we
recommend you change Seal Ring as well as the Oil Seal, if the Seal Ring is worn.
9.9 LUBRICATION
[1]
Lubrication for reduction gears of the drill motor
Inject a small quantity of grease simultaneously when replacement of consumption parts such as Carbon
Brushes and Oil Seal are made.
Use Shibuya’s genuine grease (Optional item).
The equivalent grease is MOBILUX EP1, Lithium type No. 1 Grade.
How to inject the grease is explained as follows;
1)
Unscrew a Hex. Socket Plug of Grease Inlet with Allen Key (5mm)
(Optional Item)
2) Inject approx. 2cc of the grease from the inlet. Grease Inlet
3) Tighten the Hex. Socket Plug to cover the inlet.
[2]
Lubrication on the thread of the Spindle
Lubricate the thread of the Spindle with some grease and then attach the Core-Bit.
The lubricant on the thread makes the detachment of the Core-Bit easier after drilling.
[3]
Lubrication on the Column and Leveling Bolts
Put some spray-oil to the Column and Leveling Bolts.
NOTE
Low viscosity type grease is used for this machine. As the grease lasts long comparatively, it should basically
be sufficient to replenish the grease when Carbon Brushes and Oil Seal are replaced. If the grease is
replenished very often, the Gear Case will be full of the grease and it could make extra friction to reduce the
drilling performance.
