Operation, maintenance and lubrication of electric starters
Operating instructions
Do not leave the star ter switched on longer than 10 seconds wi th out i nt erruptio n. Be -
fare swi tching on again, wa it 1 m inut e to allow the starter to cool and the battery to
re co ver. If the re is a grati ng of teeth, switch o ff starter immedi ately and repeat starting
attempt. Let go the s tarter as soon as th e engi ne runs under its own po wer .
Should the system not be provided wi th a st arter safety device, neve r switch on the
starter until the engi ne or the pinion have come to rest, as o th erwise damage wil l be
caused to pin ion and gear rim.
If
the eng ine does n ot star t after some starti ng atte mpts, further start in g attempts w ill
serve no purpose and wil l on ly lead to exhaustion of the ba tt ery. The fault shou ld be
sought and remed i ed (check the fuel supply in particular ).
Maintenance
Danger of short circuits arises when work is carried out on th e e lectrica l _ components
of th e built -in starter. It is therefore strong ly recommended, before carrymg out such
work, that th e eart h l ead be disco nnected fro m the bat t er y. Do n ot place tools on th e
battery!
Carbon brushes
The condit i on of the carbon brushes should be checked periodically. Afte r removing
the retain ing strap (2, Fig. 35) of the sole noi d-co nt rol led starter or screwi ng off the
cap (3, Fig. 36) and ta king out the fuse, th e com pensati ng was hers and the cap (2,
Fig. 3 6) of the i nertia - pinion typ e star te r, th e spring which pre sses the relevant carbon
brush on to the commut at or should be raised , preferably with a hook (take care not to
bend sp ring to one si de and n ot to raise it l onger than necessary). No w check that th e
carbon brushes can easily be moved in their guides in the brush holder .
The c
arbon br ushes and brush ho lders must be kept fre e of dust, oil and grease. If
these parts are dirty or jam, they s houl d be cleaned wi th a clean gasoline - damped
rag ( not with was te woo l, as this easily sheds fibres) and we ll dried.
Do not sa ndpaper, fi le or use knives on the brigh t gr ound su rface of the carbon
brushes. Bl ow out the brush ho l de rs well . If a carbon brush is broken, unsoldered or
so worn that the spring or the sol dered-i n s trand in the br u sh is in da · nger of strik i ng
aga inst the brush hold er, then it sh ould be replaced. (U se on ly BO SC H carbon
brushes.) Wh en fi ttin g th e carbon br ushes, car e should be tak en that th e spring does
not strike aga inst the brush.
When fitt i ng the cover st ra p (2, Fig. 35 ) of the sl i ding pi n io n starter , care sho uld be
take n to ensure that the locking clasp lies on the m id dle of a web; the sealing strip
glued into the st rap s hould closely fi t eve rywher e.
