11.0 Options manual: ST170 FlexFraze-Mower
The MAREDO ST170 FlexFraze-Mower is designed as a light renovation head. Be
careful not to overload the MAREDO STrac 700 while using the ST170 head.
11.1 First start: After connecting the ST170 to the STrac 700 (See 5.2 ST head
connection) It is important to start always start at a working depth adjusted at 0
mm. Working depth can be adjusted by the two quick adjusters on the front
roller. Actual adjusted working depth can be checked by reading the depth
indicator decals on the front of the ST head. Working depth can be increased
gently until the desired result is accomplished.
11.2 Lock ST head: The ST170 can be locked in two ways:
11.2.1 Lock left to
right rotation pivoting
around the central
connection pin:
Locking bolt in position A
= fixed position.
Locking bolt in position B
= flexible position, ST
head can pivot around
central connection pin.
11.2.2 Limit forward
to backwards pivoting:
Option A: 2 x pushrods.
Standard B: 1 x locking strip with adjustable
hole position.
11.3 Check chain drive: After the
first 8 working hours the side chain
drive needs to be checked and re-
adjusted if needed. After that, every
100 hours the chain drive needs to be
checked.
To tension the chain first loosen the
two nuts ‘A’ on the inside of the PTO
cover. Next use tensioner ‘B’ on the
underside to tension the chain by
moving the whole top sprocket tensioning assembly upwards. Tension till the
chain can be pushed in 5 mm/ 0.2”. If the top sprocket tensioning assembly is in
the top position and the chain is still too loose, re-adjust the sprocket tensioning
assembly all the way to the bottom and check by folding the chain if it can be
shortened with one chain link. When possible, remove one chain link and re-
tension.
11.4 Maintenance: Clean and check for broken or loose parts. Only use original
MAREDO spare parts. Always clean with low pressure water or compressed air.
Never use a high-pressure washer.
