Maintenance - Surtek CZ616 Manual De Usuario

CAUTION: If switch lock is ON, cutter will
start as soon as it is plugged in. To disengage
lock, pull trigger-switch and press lock-button,
which will pop out.
WARM-UP
In cold weather, warm up unit for 30~60 sec-
onds so that the hydraulic oil reaches the prop-
er viscosity. Pull trigger switch to extend piston
and release when it has reached its full stroke.
Repeat 15~20 times.
STOPPER ADJUSTMENT
The adjustable stopper functions to maintain
the rebar in the correct position during cutting
and must be properly set for each size of rebar
before making a cut.
1. Screw in stopper to
provide sufficient clear-
ance for rebar.
2. Insert rebar
into U-shaped support.
Make sure that rebar is
resting on the base of
the support.
3. Keeping rebar at right-angles(90˚) to front
cutter block, screw out stopper until it is just
touching the rebar. Once set, the stopper
needs no further adjustment while cutting re-
bars of the same diameter, but must be re-set
for a different size rebar.
CAUTION: Failure to correctly set the stop-
per will result in excessive wear of cutter blocks
and may cause cut end to fly out.
CUTTING
1. Insert rebar between stopper and front cut-
ter block, making sure that it is properly seated
in U-shaped support.
2. Pull trigger-switch and keep depressed while
piston advances and rebar is cut. (If switch is re-
leased at an intermediate point, piston will stop.)
3. When cut is completed, release switch. Pis-
ton retracts automatically (Note that switch
cannot be re-activated until piston has fully
retracted.)
POINTS OF ATTENTION
1. Be especially careful when cutting off short
lengths (30c m or less) as the cut end tends to
fly out.
CAUTION: Flying ends are a hazard to all
personnel in the vicinity. Erect safety screens.
2. Do not cover air vents.

fully
CARE: If events are covered, motor will over-
heat and may burn out.
3. If hydraulic oil exceeds 700˚C (1580˚F) in tem-
perature, power will drop. Allow unit to cool
before resuming operation. (Be particularly
careful in summer, when the aluminium pump
case heats up quicker.)
4. If a drop in power is observed and motor is
unusually hot, check carbon-brushes (see main-
tenance section).
5. If piston should ever fail to retract complete-
ly, push rear cutter block backwards to manu-
ally retract piton.
CAUTION: Use a rebar or flat metal bar for
this purpose. Never push cutter block with any
part of the hand, even if gloved.
Once piston has been retracted, pull trigger-
switch long enough to partially advance pis-
ton. Unplug unit. Check piston and housing for
accumulated dirt and iron filings that may be
jamming the piston.
If, after cleaning, piston still does not automat-
ically retract when fully extended, the piston
itself may be damaged. Return the unit to an
authorized agent for repair.

MAINTENANCE

CUTTER BLOCKS
Before using, always check that the two bolts
on each cutter block are properly tightened.
Using a loose block will result in damage to
block and housing. Also check condition of
cutter blocks. If either cutting edge is dull or
chipped, remove retaining bolts and rotate
both blocks so that two new edges come into
use. Replace and tighten bolts. (each block has
four cutting edges). When all four cutting edg-
es have been used or if either block is cracked
or otherwise damaged, replace both blocks.
CAUTION: A loose or cracked block may re-
sult in injury to operator.
CLEANING
Cleaning cutter every day, preferably immedi-
ately after use.
CAUTION: Wear gloves to protect hands from
metal splinters. Do not use an air-gun: blasting
with air can cause metal filings and/or dust to
get into eyes and respiratory system.
1. Disconnect unit.
2. Wipe or brush away all dirt and metal fil-
ings. Pay particular attention to the lower half
