A letter ro the Driver:
We can, wlth a clear conscience, assure you that your 'rPerle,r was de-
signed by experts and built by effj-cient, specialised craftsmen from the
very best naterlals. The ?rade Press has described this genuine EINKEI
creation - perfecteC only after the severest trlals over' rnany thousand.s
of oil-es i testing - asrra shi"ning exanple of present-day freedorn from
rnalntenancerr, a statement with which erren the so-caIled "first-tine-
driver" must agree in every respect.
In short, the EEINKEL people have done everything which is humanly
possible so that you can enjoy the troubfe-free pleasure of your 'r?erle"
for a long time. Eo{rever, thls depend.s a little on you.
You need neither atten.l Iectures at a Technical College nor attend a
mechanicsr course. It wil-L be qui-te suffrcae[t to read this ],ittIe book-
let and. follow its sj-mp1e instructions. fn special circumstancei, go
confidently to see your ffiINKEI Dealer, who, to a certai.n extent the lo-
ca1 representative of our After-Sales Service Department, will be ready
to give you a helping hand or a word of advice.
The 'TPERLE" will thank you for it and always make you justly proud of it.
Eappy driving !

An important point to watch is that the lighting s]'stem nust a}vays be
switched off whilst the engine is being started.
Any one-til:le cyclist who desires a taste of good old timesr however, can
start his "Perfe" on the roughly 0.2 h.p. power of his 1eg nuscles. Read.

Starting on a hill gives the beginner a certain anount of trouble, because
the vehicle, following the 1aw of gravlty, has a natural tendency to go
backrards. He does not know whether to counteract this natural backward
novernent with both feet 'rdirect'r, namely by braclng them on the ground., or
by a foot or hand brake. Firstly apply the hand brake!
Xeep the hand. brake on until the engine has fired., the clutch has been taken
off, the vehicle put i.nto first gear and the left leg is free to support the
rheel. Now, with the right foot on the pedal (as lf intending to pedaL for-
xards, not backward.s!), stop the "Perle" fron running backwards. The left
hand can now slowly release the clutch leverr whilst the right gradually ac-
celerates. The engine will thank you for a llttle help from the peaials at the
outset, as the starting resistance on a hill- i-s qulte something.
Driving experience will show that steep downhill slopes should be taken in
the sane gear as would be used for driving up the same s1ope. The first gear,
which provides an addltional braking action on the engine, should therefore
be used. As is the case with any two-stroke engine' the effect of this 'raddit-
ional braking" action of bottom gear is not such that the driver need not call
on his front or rear wheel brakes. If the downhill slope is relatively long
and the front and rear brakes are used alternatelyr no strain is placed on them
and the driver is never in danger of reaching dangerous speeds unexpectedlj.10

As the engj-ne of the rrPerlerr gets its lubrication solely fronr the oil
contained in the fuel, it rnight well get too 1itt1e lubricant on pro-
longed downhi.ll slopes if the throttle is closed all the time. It is
therefore recommended. that in such cases the clutch be pul1ed in and
the throttle briefly but strongly opened up, so that the englne is
thoroughly lubricated.
Any former cyclist who stil1 wishes to get some of the old sport out
of his rrPerle" can d.ispense with the comfortable kick-starter and get
his moped gojng in crack-cyclist fashi.on by nedalling. ?his is how to
do it r
Open up throttle a little - pult clutch lever right in -
put noped into second gear - start pedalling - sIowly re-
lease clutch lever - briefly depress decompression lever
at the same time and the 'rPerle" engine is "therer'.
If the engine is co1d, the lever controlling'. the auxiliary starter should
be manipulate d..
Naturally, the "Perle" can also be ridden as an oriinary bicycle, i.e.
entirely without the englne vrorkin,q. Thanks to the ideal position of the
seat and the mopedrs easy runnlng, pedalling without the engine is by no
means the drudgery one might imagine. Just put the moped into second. gear
on the flat and into flrst on slopes and lock the clutch (see l,ig. KD 15
on page l{). 1l

STOPPING AND PARK]NG
is also very slmple with the "Perle". So long as there is no ernergency,
speed. can be reduced reasonably well before the stopplng point; wlth the
throttle closed, the vehicle can gradually come to a standstill, so that,
to stop it, only the clutch need be pu11ed in, the twist grip gear shift
ssitched to position "0" and the brakes apilied. A slight pressure on the
deconpression lever will stop the englne. ff tris siop narks the end of
the day for the noped, it would have been as well to shut off the luel
cock before stopping the .en6ine, so that the 'rlerle'r is :lot left for any
length of tlme with fuel in the float chamber' otherwi-se the fuel evapor-
ates leaving the oil on lts own in the float chamber' and this can give
trouble rvhen the moped is next started.
The moped can now be parked or left leaning agaj.nst a wa1l. In this respect '
it nust be remembered that the stand serves nerely to park the moped and
must be raised before the driver takes his seat, because this stand ls in-
tended. to take the weight of the mopedl but not that of its d.river.

Cleanlng and Care.
Dirt does not easlly adhere to the harmoniously snooth outer surface of the
"Perle" frame. lio''vever, if, durlng a long ride ln bad lyeabher, any dirt should
have coflected on the other parts, loosen it with warn water, softened b/ th.e
adCition of a nild cLeansing agent, and thel rinse off. In an emergency, :1ear,
cold tap-?ater rvi11 do it also. Under lio clrcunstances, though, should I ::trong
jet ol water 'le used, since ihis forc.es particles of Cirt through the bearing
seals and water is nc good either for the aj.r filter or lor the generator
dynamo.
A gooC deal of dirt collects in thc corners where the cool^ing fins join the cy-
linder, bccause this is so close to the road surface. 1f this dirt is al1or.red
to remain there undisturbed, .t can seriously affect the cooling and thus en-
danger the working of the cylinder. It should., therefore, be loosened vrith soft
sater and brushed out - though, naturally only when the englne is cold..
After this ivash, the "Care" stage starts, fron top to bottom. The foam rubber
seat is cleaned with a find'washing agent and the frame isith a suitable polish
(such as Polifac lvith silicones). Ttre engine should be washed lri-th a petrol
cleaner, paraffin or with Cehapon (fo11or, ihe makerrs instructions closely),
and if there is still tine, any drj.ve:: particularly ccncerned vith care of hi.s
'rPerlerr can also give the chromium-pl-ated parts a thin coating of vasellne or
slnilar grease.
lflaintenance,
The "Perlerr engine is positivell' lubricateC by the adJltion of oil to the fueI,
eliminating maintenance in its main sense. 17

After roughly 2000 kllometresr travelling, the three screws (KD l5) should
be undone and the exhaust unit re;:oved anC di"smantled. ?he ir:slde of the
si.lencer and the exhaust slit i!: the cylinder should be cLeaned of any o1L
carbon residue \,rith a hardlrood scraper or a blunt netal object. Should the
output from the engine anC at ihe sa;re tir]]e its tipurr dete]:iorate even
before these 2O0O kllometres are up, then the 'rde-coke', should be carried
out correspondirrgly sooner.
The level of oi1 ir thc rearLox should be checked regularly (see detalls
on Servicing schedule) uiI--II-g " u r oil changed, .s ih" ca"e may be. The
fixst oil change at 5CC l.:r1or:eires is of particular importancel (fiS.7)
To check the oil leveL, i.inscre!v the oil-fi11er cap. ff , .,,ihen the machine
is level", the oi1 does no: coiile just up to the hoIe, then top up by ne-
cessary aiiount rrithout Jela.y (see illustration).
To chbnge the oil (rhich should a1',vays be done whilst the engine is warm),
rerjove the screw plugs fron the filling hole and oil drain and a1low all
the oId oil to run out conpletely. To make sure that every drop runs out
of the svring arm also, lift the rear wheel- off the ground.. Afterrvards,
replace the pJ-ug in the 01] drain, set the machine down on the level once
again and fill up with nex prcrlietary Sear oi1, such as "Mobj.loil C 80'rr
