[Procedure (See illustration 1.1)]

Loosen the oil-injecting screw (13), then tighten the oil-draining valve (7) clockwise. Place the mould on the center ofthe worktable (9). After tightening the screw (2), swing themanual handle (11) forward and backward to achieve the re-quired pressure. After dwelling, loosen the oil-draining valve (7) anticlockwise and remove the mould.

[The scope of application]

The instrument is mainly used in infrared spectrophotometer sample preparation of solid samples and a variety of small powder tablet molding. Widely used in catalysis, silicates, batteries, ceramics and powder metallurgy and other industries.

[Principle of Oil Channel (See Illustration 1.2)]

The oil-draining valve (7) is closed during the working process. When swinging the manual handle (11), the oil is suck from oiI poll (8) through the one-way valve (15) then it enters the big oil cylinder (6) through the one-way delivery valve (16). Thus great energy is accumulated,which produces high- pressure oil and the indication can beread on the pressure gauge (10). When opening the oil-draining valve (7), the energy unloads.

Illustration 1.2 YLJ01 Small Manual Hydraulic Press Principle of Oil Channel

[Notice]

1. LOOSEN the oil- ijecting screw (13) before operating the press.

2. Add the lubricating oil in the screw (2) and piston pump (12) regularly.

3. To avoid accident, pressurization MUST be within thepressure -range of the press.

4. It is recommended to use the clean machine oil (No. 46). Breakoil is strictly FORBIDDEN to be used in the press.

5. During pressurization, if force can be felt on the manual handle (11) with no indication on pressure gauge (10) , please unload IMMEDI-ATELY and check the pressure gauge (10) .

6. For the new or long-unused press, it is necessary to tighten theoil- draining valve (7) a little before operating the press. Then pressurizeto 20-25MPa and unload. Repeat this process twice or three timesthen the press can work properly.

7. Piston stroke MUST be within 20mm.
