of the shaft, The recommended quantity is 25 g per metre. Do not overlubricate, it could cause the grease
penetrate into the poker, Do not clean the shaft with solvent. The grease recommended is of the brand
KLÜBER LUBRICATION with the following characteristics:
Dropping point s/ DIN 51801/1 (ºC) .................................................. >220
Temperature range (ºC) .................................................................... 30 a 130
Maximum temperature during a short time (ºC) ................................. 180
Worked penetration s/ DIN 51 804 (0.1 mm). ................................... 260
Consistence s/ DIN 51 818. .............................................................. 2/3
Dynamic viscosity (mPa s). ............................................................... 3.000
Speed factor (n dm). ........................................................................ 500.000
5.- When the length of the shaft is not equal to the hose (+-10 mm) it is neccesary to repair before producing
a bigger breakdown.
6.-Every 300 hours of working is recommended to change the lubricant of the poker. To change the oil in the
poker dismount the cap. Hold the housing on a vise and tap the cap with a plastic hammer. This will help to
break the seal and to loosen the threads. Take out the old oil and fill the cavity of the cap with a light oil non-
foaming SAE40 or equivalent. Mount according to the recommendations of the following point. If inspection
reveals that the oil is thick, heavy, sticky mixture, then the grease of the flexible shaft has penetrated into the
head, and the seals have to be replaced. Follow the steps of the point 7 to replace it.
7.-To do a maintenance follow the following steps:
- Flush the parts with solvent and wipe all part.
- Examine bearings, seals and hex driver. If inspection reveals that grease of transmission has
penetrated into the head, the oil seals need replacement. When replacing seals, mount them back
to back (neoprene seal lips face away from each other).
- The purpose of the seals is to keep the oil of the head in, and the flexible shaft grease out. Be
careful not to damage the polished surface where the seals goes. When the seals are dismounted
it is recommended to change it.
- Fill the cavity of the cap with a light oil non-foaming SAE40 or equivalent.
- Apply sealant before assembling and fix the O ring. Tighten and clean the excess sealant. It is
important all the parts are tightened to avoid water and cement try to get into the head.
8.-After maintenance job and service, all the parts must be assembled correctly.
9.-Every 12 months or more frequently, depending on the usage conditions. It is recommended an
inspection be done by an authorized dealer.
