Toavoiddamagingthemachine,itisessential
tobemonitorhowlongthemachinehasbeen
operatingcontinuously(‘power‐ontime’).

Allelectricbrushedmotorsgeneratelarge
amountsofheatintherotorandstator.Al‐
thoughthemachineisfittedwithafancooler
thatdissipatestheheatproduced,ifthema‐
chineissubjectedtoextremeloads(e.g.milling
largebevels,veryhardortoughmaterials)and/
orisruncontinuouslyforalongperiodoftime,
thecoolingsystemmaynotbeabletocopewith
theamountofheatgenerated.Iftheoperator
continuestousethemachine,therotor
(armature)mayoverheattosuchanextentthat
thewindinginsulationmeltscausingashortcir‐
cuit.

Donotoverloadthemachine!

Themachinecanbecomeoverloadedif,forex‐
ample,itcontinuestobeusedeventhoughthe
bevelbeingcutistoolargeforthematerialbe‐
ingmilled,orifthecuttinginsertshavebecome
bluntandthereforeunabletopenetratethema‐
terial.
Suchconditionscanleadtolargemachinevibra‐
tionsorevenmachinebreakdownifthearma‐
tureinthemotorisbenttosuchanextentthat
Thepower‐ontimeisalwaysexpressedasaper‐
centageofonehour.
Example:
Ifthepower‐ontimeisspecifiedas50%,thenyou
canusethemachinetomillbevelsforamaximum
of30minutesinanhourandmustthenleavethe
machinetocoolfor30minutes.Ifthemachineis
subjectedtoheavyloads,thepower‐ontime
mightbe20%,whichmeansitcanbeusedfor
12minutesinanyhourandmustbelefttocool
for48minutes.Beforecompletelyswitchingoff
themachine,werecommendrunningthemachine
foroneortwominutesinidlemode(unloaded)so
thatfancancontinuetodrawcoolairthroughthe
machine.

Topreventthissortofdamagewhenmillinglarge
bevelsand/orhardmaterials,nevertrytoma‐
chinethebevelinasinglepass,alwaysusemulti‐

meansoftheoriginallockingscrews(max.tighten‐

Aseachinserthasfourcuttingedges,itcaneach
beindexedatotaloffourtimesbeforerequiring


Astheinsertsareeachapproximately11mmlong,
