Assembly and Installation

1. Open the lubricator outlet by removing plug.
   Do not remove plug from oil filled units! Cut off the pro-truding nipple with a knife; a small black point becomes visible (opening now guaranteed).

2. To start the simalube lubricator, set the gas generator to the required dispensing time (stepless in months, 1–12) using a 3 mm allen key. The lubricator is activated once the dispensing time has been set. Take the required dispensing quantity from the tables on page 11.

3. Note the starting date on the label using a waterproof pen.

4. Clear grease lines and fill them with the appropriate grease. Screw simalube onto the greasing point. If necessary, use accessories shown on page 33–39. Apply safety rules.

5. Once the set dispensing time has expired, replace empty lubri-cator with the same type or refill. Before restarting, clear grease lines and fill them with the appropriate grease.

6. The gas generator is sufficient to empty the unit once, irrespec-tive of the dispensing time set.

Security note: If the lubricator is started without opening the outlet or in case of blocked grease lines within the installation, the pressure in the lubricator can build up approx. 5 bar. At an overpressure of approx. 6 bar the lubricator breaks at the defined breaking point between housing and bottom. The pressure behind the piston releases and oil or grease can come out at the breaking point.

Warning: For applications in explosive gas or dust atmospheres, precautions shall be taken to minimize the risk from electrostatic discharge or propagating brush discharges at the product surface. Cleaning of the surface shall be done using a damp cloth.

The correct functioning of the lubricator can only be assured if recommended lubricants (see table on page 14) and original simalube accessories are used, and if the install-lation, operating and maintenance instructions are closely followed. The manufacturer cannot accept any responsibility for damages as a result of ignoring the instructions mentioned above. Important: Before putting simalube into operation, fill extensions and the lubrication lines with the appropriate simalube greases (cartouches SL01 …SL26) using a grease gun. Use only original accessories.

Temperature/Output rate
The output rate can be adjusted as required, depending on the ambient temperature (see table).
Example: You want to set the dispensing time for a 125 ml simalube for 180 days.
Ambient temperature: 20 °C Ambient temperature: 55 °C Setting: 6 Setting: 7

• Use larger dispenser with longer dispensing time
• Use smaller dispenser with shorter dispensing time

• Use larger dispenser with longer dispensing time
• Use smaller dispenser with shorter dispensing time simalube 250

• Use 2-fold adapter
• Use smaller dispenser with shorter dispensing time

The values relate to laboratory conditions, SL01 with no counterpressure. At low tempe-ratures in particular, the values may vary between one grease type and another. The dispensers must be replaced once the dispensing time set has expired, even if they are not completely empty.

The grease quantity dispensed per day is influenced by:

• counterpressure/resistance from the grease lines
• ambient temperature
• viscosity of the grease

Start-up time

The lubricator requires a certain start-up time until the lubricant is first dispensed. The start-up time varies in line with the volume dispensed, dispenser size and operating temperature selected. At 20 °C ambient temperature and a dispensing time setting of 12 months, the dispenser outputs the lubricant within one week. The start-up time doubles at low temperatures (–20 °C) or with small dispensers (30 ml).
You can reduce the start-up time in such a case by setting a dispensing time on the
lubricator of one month for one to two days and then changing to the desired dispens ing time.

Notes:
In order for the unit to function reliably, it is important to have clear, filled grease lines. It must be ensured that the grease lines are not blocked. Consequently, the grease lines should always be cleared with a grease gun before starting.
The simalube can be re-adjusted or switched off during operation. The values on the gas generator relate to laboratory conditions (see page 10). Depending on the temperature and setting, it may take several hours (or several days in the case of long-term settings) until the lubricant is first dispensed. The user must check the operation of the simalube regularly.
Grease lines should be no longer than 0.5 m. Recommended bore diameter: 6–8 mm. Resistance in grease lines has to be minimized, narrow passages and right angles should be avoided. Use a mounting support in the event of strong vibrations or high acceler-ations (for accessories, see pages 33–39). Use the pressure booster (art. 230.1010) simalube IMPULSE connect with long lubrication lines or high back pressure.
The simalube may only be used to supply a single grease point. No branches may be made. Once the lubricator is installed and activated, it must not be removed and mount-ed onto another lubrication point.

Recycling Instructions

1. Unscrew gas generator and dispose of complete unit for battery recycling (see above). Note: Do not detach lubricator near an open flame.
2. Dispose of empty housing for plastic recyc-ling. If the lubricator still contains lubricant after use, please dispose of it in accord-ance with local regulations.

Filling and Refilling (for small quantities)

Filling with grease

1. Push piston all the way forward by blowing gently with compressed air or with the aid of a plastic rod (7 mm diameter), towards the bottom or opening.

2. Screw on refill nipple (Art. 290.3012) and connect grease gun, or screw connector nipple (Art. 290.3013 or 290.3014) onto grease gun. Keep the dispenser pressed to the adapter during the filling process so that you do not have to screw on the refill nipple again. Press grease into the dispens-er. Avoid air bubbles when filling the unit. Continue the filling process until the piston has been pushed all the way back. Do not overfill! Caution: Lever presses can create pressure of up to
   80 bar, which is enough to destroy the dispenser.

3. Use closing nipple if the dispenser is to be stored.

4. Position gas generator (make sure the O-ring is positioned correctly) and attach firmly with a 1.5–2.0 Nm torque key.
   Always use original simalube gas generators.

5. Clip in cover disk.

6. Note grease type and filling date on the label.

Filling with oil

1. Push the piston all the way back (to- wards the gas generator).
2. Pour in oil through the opening at the bottom.
3. Position non-return valve (yellow, Art. 290.5060)
4. Continue as above.

Refilling with grease or oil

1. Remove cover disk.
2. Unscrew gas generator (SW 21) and re-cycle with other batteries. Never remove near an open flame! Then continue as above for filling with grease or oil.

Note:
To ensure that the simalube lubricator operates reliably, only greases that have been tested and approved for use with the simalube should be used. In particular, it is important to ensure the good stability of the grease against bleeding of the base oil and a low consistency class (max. NLGI 2). No guarantee claims will be accepted when dispensers are filled by the user or not explicitly approved lubricants are used. If in doubt, please contact our technical department or your local distributor.

Lubricants

The standard lubricant range suitable for simalube includes modern high quality lubricants tested and modified for the special requirements of grease and oil dispensers. Datasheets are available online for all lubricants (www.simatec.com). Please refer to these datasheets for the instructions/safety regulations of the grease/oil manufacturers.
