Lubrication
8.2.1
Daily
Mainshaft – Wipe off any deposits of grinding dust with a dry cloth or brush ensuring the
keyways are kept clean. Using a fine spray oil, such as WD40, spray the whole shaft. Use
an excess of WD40 in one place and slide the grinding wheel assembly backwards and
forwards over that area in order to wash out thoroughly the inside of the sleeve. This will
remove any build up of material and ensure the free movement of the assembly along the
shaft.
After thoroughly cleaning the shaft, dry and ensure that no oil remains at all before use.
It is essential that the grinding wheel sleeve and nut can be moved freely along the entire
length of the mainshaft at all times.
Occasionally lubricate the contact areas of the fork driver (with the sleeve and nut)
with “MOLYCOTE
®
” (Molybdenum Disulphide), this will impregnate the surface. Excess
lubricant / propellant should be wiped off again after a short time.
NOTE
Never apply nor leave any oil or grease on the mainshaft during use.
For extended periods of down-time spray on “bright” areas with Bernhard’s Protective oil
– clean off with Bernhard’s Clean and Lube spray or WD40 before use.
8.2.2
Weekly
Spray WD40 or equivalent onto all moving parts (the mainshaft must be completely dried
before any grinding is carried out). This includes the threads under the feed column
handwheels, the reversing bar and the shafts on which the fork and pickup assembly run.
The majority of bearings are either oil impregnated or are ball races and, apart from those
mounted in special sealed housings or fitted with grease nipples, require the occasional
drop of oil. These include the reel drive coupling bearings and the pressure lever pivot
bearings.
8.2.3
6 Monthly
Chain and idler sprocket require cleaning and oiling.
Examine belts for wear and tension.
DO NOT OVER-TIGHTEN.
Examine fork assembly for wear – some slight discolouration may occur, this is not a
problem.
8.2.4
Yearly
Mainshaft bearings are pre-packed with grease.
IF
grease nipples are fitted
ONLY 1
SMALL SHOT
of grease should be applied annualy.
These bearings run warm/hot, that IS OK. Extra grease will not reduce the temperature,
more likely the reverse, the seals and subsequently the bearings may fail prematurely.
