Cylinders are connected with pump by the help of high pressure hoses of type 4SP

DKOS/DKOS about inner diameter 6mm. Hoses are supplied as the separate product

in basic length 2m or in other length to 6m according to wish of the customer. Hoses is

fitted on both ends with screw M18 x 1,5mm.

! CAUTION

During use of long hoses connection between pump and hydraulic cylinder is

necessary ALWAYS judge individually, whether amount of oil in houses do not limit

use of hydraulic cylinder lift.

Note: 10m of hose of inner diameter 6mm represent cca 0,3l oil.

6.3 POSITION OF CYLINDER DURING LIFTING OR LOWERING

During lifting or lowering of load the bottom of cylinder shall sit on firm a large enough

so as to avoid sinking of the cylinder. Pay attention the cylinder stand vertically. Axes

of piston can be diverted at max. about 3°.

! WARNING

ALWAYS make sure the jack stands vertically during lifting.

6.4 LIFTING A LOAD

Before lifting a load make sure the piston

nut is not screwed up to prevent its full

insertion into the cylinder. Piston shall be in

its initial (lower) position.

Lifting is provided by the oscillatory motion

of the hand lever of the pump. Instructions

for operating the pump are stated in

separate manual that is delivered to each

pump. After finishing the lifting ensure

piston against self-dropping by the nut - see

fig. 6.5.

! WARNING

ALWAYS before lifting make sure, the piston matrix does not prevent its full insertion

into the cylinder.

ALWAYS pay attention during lifting so as not exceed maximum height of lift.

NEVER lift piston of cylinder over red marked groove, which is under screw

of piston!!

ALWAYS ensure the piston by the matrix after termination of lifting.

6.5

LOWERING

LOAD

Before lowering a piston, at first slightly lift up the piston by several pendulum motions

of the hand lever and then unscrew the piston matrix to its top position.

Lowering the piston and speed of lowering control by releasing the screw of the drain

valve thanks to slide on hand lever. Before lowering the piston in dusty environment

we recommend to clean up the surface of the piston.

6.6 TEST BEFORE THE USE

! CAUTION

(1) Visually check the cylinder and support area, whether they are without defects.

(2) At first, look again at the previous articles of this manual and make sure that all

steps were done correctly and cylinder is correctly connected with appropriate

pump.

(3) By the move of pump lever check the function of the cylinder without a load.

(4) Provide several lifting and lowering with a suitable load (10% up to 50% capacity).

(5) At the same time check the cylinder and pump, whether at interruption keep load

without a drop of piston.

(6) Check, whether there is no outflow of oil due to the leakage.

(3) When operating by more persons ALWAYS there must be determined one worker

trained with safety of work responsible for manipulation with the cylinder.

(4) The operating staff must have a clear and unobstructed view of the whole working

area before starting the work. When it is not possible, one or more persons must

help to supervise in the nearby area of the hydraulic cylinder.

(5) The operating staff must check, whether the entire work place is safe and whether

there is as possibility of escaping from this area in case of endanger, before

starting to operate the cylinder.

(6) During the work with the cylinder the suitable distance of the operating staff from

the load must be kept. It is prohibited to lift or lower bulky loads preventing to keep

sufficient safety distance.

8 INSPECTION OF CYLINDER

8.1

INSPECTION

8.1.1 Inspection classifications

(1) Initial inspection: precedes first use. All new or repaired hydraulic cylinders shall be

inspected by a responsible qualified person to ensure the qualified fulfillment of

requirements of this operation manual.

(2) Inspection procedures of hydraulic cylinders operated regularly are generally

divided into two classifications based on the intervals at which should be performed.

The intervals depend on the condition of the critical components of the hydraulic

cylinders and the degree of the wear and tear, deterioration or malfunction. The two

general classifications are herein classed as daily and regular ones. The respective

intervals are defined as follows:

(a) Daily inspection: visual inspection, carried by the operator, designated by the

user on the beginning of each use.

(b) Regular inspection: visual inspection carried out by the qualified person

designated by the user.

1) normal operation – once per year,

2) heavy operation – twice per year

3) special or infrequent operation – according to the recommendation of the qualified

person at first usage and according to the directions of the qualified person (workers of

maintenance).

8.1.2 Daily inspection

Regarding parts such as those recommended in the section 8.2(1) „Daily inspection“

verify, whether the girder clamp is without any defect. Provide this inspection also

during operation in the interval between regular inspections. Qualified employees will

determine whether any defect or damage can constitute a hazard and whether more

detailed inspection is necessary.

8.1.3 Regular inspection

Complete inspections of the hydraulic jack perform as recommended regular

inspections. These inspections may be performed with the hydraulic jack in its normal

location. Recommended regular inspection specified in the section 8.2(2) shall be

performed under the supervision of qualified persons that will determine, whether it is

necessary to repair the girder clamp. These inspections shall include the requirements

of the daily inspection as well.

8.1.4 Occasionally used hydraulic cylinder

(1) Hydraulic cylinder, which has been idle for a period of one month or longer but less

than one year, remit to the inspection conforming to the requirements of the section

8.1.2 before follow-up putting it into operation.

(2) The hydraulic cylinder, which has been idle for a period of one year, remit to the

inspection conforming to the requirements of the section 8.1.3 before follow-up putting

it into operation.

8.1.5 Inspection record

Always keep the record of the performed tests, repairs, inspections and maintenance

of the girder clamp. Dated inspection records perform in time intervals specified in the

section 8.1.1 (2) (b) and such records store in an accessible place designated by the

user.

Defects discovered by the inspection or reported during work must be announced to

person responsible for safety designated by the user.
