counterclockwise one-qu rter turn m xi-
mum to loosen, move h ndle to desired
position nd tighten knob to lock h ndle in
pl ce.
B - THROTTLE CONTROL - this is push-
pull type throttle control which c n be
locked t ny desired bl de speed to meet
v rying job conditions. To use, simply push
or pull the throttle control to obt in the
desired bl de speed. To lock the throttle t
the speed, turn the control clockwise. To
unlock the throttle for further djustments,
turn the control counter clockwise pproxi-
m tely 1/4 turn.
C - DYNA-CLUTCH LEVER - this is
p tented fe ture which cts s s fety
device to stop the trowel from spinning out
of control if the oper tor lets go of the
h ndle. It lso llows the oper tor to control
the eng gement nd diseng gement of the
trowel bl des independent of engine speed.
To use, simply move the lever ll the w y up
to the RUN position to eng ge the trowel
bl des. To stop the bl des from turning,
push the lever ll the w y down to STOP
position. In the event th t the oper tor lets
go of the h ndle while the bl des re
turning, the centrifug l force from the swing
of the h ndle will throw the Dyn -Clutch
lever to the STOP position. This prevents
the unit from spinning out of control nd
c using injury to personnel or d m ge to the
trowel nd fresh concrete. Since the Dyn -
Clutch system diseng ges the bl des from
the engine, r ther th n shutting down the
engine to stop the bl des, time is s ved in
getting the unit oper ting g in. The
oper tor simply moves the Dyn -Clutch
lever to RUN position inste d of h ving to
rest rt the engine nd re djust engine speed.
D - TILT ADJUSTMENT KNOB - djusts the
ngle of the bl des for different curing
st ges nd conditions of the concrete.
Turning the knob clockwise incre ses the
ngle of the bl des to the concrete. Turning
the knob counterclockwise fl ttens or
decre ses the ngle of the bl des.
E - ProPitc  Handle Option - djusts the
gnle of the bl des for different curing st ge
nd conditions of the concrete. Lift h ndle
upw rds to incre se ngle of the bl des to
the concrete. Depress trip button to rele se
lock nd decre se the ngle of the bl des.

Introduction
TO ADJUST TILT LOCK NUT--The tilt
lock nut is loc ted on the tilt rod ssembly.
Using the lifteye, r ise the trowel with n
overhe d cr ne. B ck off tilt knob until there is
enough c ble sl ck to ccess the tilt lock nut.
For more tilt, loosen lock nut set screw nd turn
lock nut tow rds tilt knob, 1 turn, nd lock set
screw. Cr nk knob to full tilt position nd
check cle r nce between the tilt lever nd
ge rc se for 1/64" (p per thickness). Repe t
djustment if required.
NOTE: Cables may stretc over time and
may need to be replaced if full tilt is no
longer obtainable.

TO ADJUST ProPitch LINKAGE
Rod--The link ge rod is f stened to yoke end
nd swivel by two nuts. To djust follow the
steps listed below.
1. Using the lifteye, raise the trowel using an overhead
crane.
2. The lower end of the linkage rod is connected to a
yoke and held in place with two (2) nuts. Loosen the
nut on the upper end of the linkage rod to allow
slack in the tilt cable when the ProPitch handle is in
full tilt position.
4. With handle in full tilt position, adjust the nut on the
backside of swivel at the upper end of linkage rod
until the proper gap is achieved between the tilt
lever and the gearcase--approximately 1/64 inch.
5. Tighten nut on the outside of swivel to lock linkage
rod into position.
6. Repeat adjustment if re uired.
NOTE: Cables may stretc over time and
may need to be replaced if full tilt is no

Operations
TO START--M ke sure the Dyn -Clutch lever
is in the STOP position. If it is not, push the
lever down to the STOP position before t-
tempting to st rt the engine. Open fuel v lve
under fuel t nk (if so equipped), open throttle
pproxim tely h lf w y down nd pply choke.
Holding unit h ndle firmly with one h nd, pull
the st rter rope sh rply with the other bout (3)
times. When engine st rts, open choke nd
djust throttle s necess ry to keep it running. If
engine doesn't st rt fter (3) pulls, open choke
slightly.
NOTE: These st rting instructions re gener l
guidelines only. Since m ny engine options re
v il ble on CF Power Trowels, consult the
ENGINE MANUAL included with the unit for
specific instructions.
TO SHUT OFF
5.5 HP & 8 HP B&S ENGINES - close throttle
ll the w y, flip grounding t b g inst sp rk plug
nd hold there until the engine comes to
complete stop.
4, 5.5, 8, 11 and 13 HP HONDA ENGINES -
close throttle ll the w y nd flip oil minder kill
switch to the OFF position.
4.5, 6, 9 & 11.5 HP ROBIN ENGINES - close
throttle ll the w y, depress kill switch button
nd hold down until engine stops completely.
NOTE: These stopping instructions re gener l
guidelines only, consult the ENGINE MANUAL
included with the unit for specific instructions.
INITIAL OPERATION--With engine st rted
s instructed previously nd t oper ting tem-
per ture, djust speed to bout h lf throttle.
Hold the h ndle firmly with one h nd nd move
the Dyn -Clutch lever to RUN position to
eng ge the trowel bl des.
FLOATING OPERATION
Att ch flo t or combin tion bl des to the trowel
rms, nd when the concrete h s set sufficiently
to support the weight of the trowel, pl ce the
unit on the concrete. St rt the unit nd eng ge
the bl des s previously instructed. Using the
tilt djustment knob or ProPitch h ndle,
djust the bl des to the flo t position--bl des
should be s fl t to the concrete s possible with
enough tension kept on the tilt djustment c ble
to prevent the unit from d ncing or ch ttering.
Guide the trowel over the concrete in circul r
b ck nd forth motion. Under norm l condi-
tions, you should be ble to flo t 30 x 30 foot
re in pproxim tely 15 minutes.
This oper tion will bring the w ter nd fines to
the surf ce, llowing for smoother finish when
finishing the concrete.
FINISHING OPERATION
After flo ting, llow the concrete to set until it
will support the weight of the trowel. Set the
pitch to pproxim tely 1/4" to 3/8" on the
bl des. If the bl des st rt to dig into the con-
crete, decre se the mount of pitch.

Maintenance
MAINTENANCE, LUBRICATION
AND ADJUSTMENT
To get long nd trouble free service from your new
CF Power Trowel, it is essenti l to perform peri-
odic m inten nce on engine nd m chine mech -
nisms. Follow the guidelines listed below:
LUBRICATION
A. ENGINE CRANKCASE
Daily--check oil level in engine. Engine w rr nty
is VOID if it is run without oil. Add oil s re-
quired to keep cr nkc se full. Engine oil should
be ch nged every 250 hours of oper tion, or once
ye r, whichever comes first. See Lubric tion
Specific tion section for engine.

justment/Lubrication/Trowel
Gearcase/Arm Bearing
These oil requirements re gener l guidelines only,
for specific requirements consult the ENGINE
MANUAL included with the unit.
B. TROWEL GEARCASE
Daily--check oil level in ge rc se. Trowel w r-
r nty is VOID if run without oil. Oil level should
fill the sight plug, loc ted on the right side of the
ge rc se, when the unit is t rest on level sur-
f ce. Add oil s required to keep oil level t cor-
rect height. Ge rc se oil should be ch nged ev-
ery 250 hours of oper tion, or once ye r, which-
ever comes first. See Lubric tion Specific tion
section when dding or repl cing ge rc se oil.
C. ARM BEARING
Mont ly--gre se rm be ring through the gre se
fittings in the spider. There re (3) fittings on (3)
rm trowels nd (4) fittings on (4) rm trowels.
Pump gre se into e ch fitting until cle n gre se
comes out of spider t either end, thoroughly cle n
excess gre se off from spider when ll rms h ve
been gre sed. See Lubric tion Specific tion sec-
tion for gre se requirements.
D. THRUST BEARING
Weekly--gre se with ny gr de 1 Lithium b sed
gre se to purge out ny dirt or w ter. Wipe off
excess gre se. See Lubric tion Specific tion
section for gre se requirements.
Yearly--for be ring lubric tion remove thrust
be ring nd cle n thoroughly. Inspect for
d m ge nd repl ce if necess ry or rep ck with
gre se nd reinst ll. Refer to Spider Assembly
