5.0 First start and first use
After first unpacking (See Separate MAREDO ST unpacking manual) it is important
to first check the STrac 700 before starting it for the first time:
5.1 First checks and engine start
5.1.1 Check if all protection covers are in place and undamaged.
5.1.2 Check if the engine oil level is correct. This can be checked by pulling out
the grey oil level stick which is located on the front of the HONDA engine (see fig.
1). Oil level should be between the marks.
5.1.3 Check if the hydraulic oil level is correct. This can be checked by pulling out
the oil level stick in the hydraulic tank. Make sure the STrac 700 stands on a flat
and level surface. This dipstick is easy to reach through the hole in the top cover.
The oil level should be between the bottom and top mark. NEVER START THE
ENGINE WHEN THE OIL LEVEL IS TOO HIGH OR TOO LOW. Drain oil when the oil
level is too high or fill with extra oil when the level is too low. See 2.0 Technical
specifications for the correct oil.
5.1.4 Check if the PTO lever is in the top position: O (see fig. 2) PTO OFF
5.1.5 Take all needed safety precautions before and during filling the gasoline
tank. Make sure not to spill gasoline over the engine. In case gasoline is spilled
over or beside the engine, the engine may not be started for 20 minutes.
Place the tank cap back right after fuelling.
5.1.6 Check and open the fuel valve on the engine (see fig 1.)
5.1.7 Put the motor switch to ‘ON’ (see fig 1.) and check if the Emergency Stop
on the handlebar is in its top position: ON
5.1.8 For a first (cold) start put the Choke lever on ‘Choke’ and Throttle on 40 –
50%
5.1.9 Pull engine cord gently towards you. Make sure not pull too hard to prevent
injuries. The engine should now start within 1 –2 pulls. For a Cold start leave the
Choke on for about 10 seconds and then switch the Choke off. The Engine should
now run smooth. (In case it does not please see 7.0 Trouble shooting). Give the
engine some time to warm up.

5.2 ST head connection
5.2.1 After unpacking MAREDO ST heads (see Separate MAREDO ST
unpacking manual) they are placed on a MAREDO ST Trolley. Position the
MAREDO STrac 700 with the rear of the machine about 1 m/ 3’ in front of
the ST head which needs to be connected. The front of the ST head can
be recognized by the central connection pin which is located on the front.

5.2.2 Place the rear wheels in the position beside the STrac 700 as shown
in the image below. To do this the square pin needs to be pulled out. Next
the wheels can be put in the position besides the machine and re-locked
in place by the square pin see figure 3 below.
5.2.3 Remove the round pin which locks the rear ‘door’ bracket in place.
Either the left or right pin can be removed. Next the rear ‘door’ bracket
can pivot open giving all access to the hydraulic hitch. See figure 4.

5.2.4 Push the hitch control lever on the steering boom forward till it
clicks in float position. This makes that the hydraulic hitch can be moved
up and down by hand. Roll the ST head on the MAREDO ST trolley
forwards towards the STrac 700. Slide the central pin of the ST head into
the hole of the hydraulic hitch of the STrac. When the pin is inserted all
the way, it can be locked in place with an R-pin.
5.2.5 Connect the PTO to the ST head. Make sure to have the push pin of
the PTO facing down to be able to reach it and push it in.

NOTE: Never connect the PTO to the ST head with the engine
running. The engine must be switched off during connection and
dis-connection of ST heads.
5.2.6 Close the rear ‘door’ bracket and re-insert the locking pin. Lock this
pin in place with the secure pin. Check all connections and then start the
engine and lift the ST head by moving the hitch control lever on the
steering boom backwards. The ST head is now connected to the STrac
700.
6.0 Adjustments
Several adjustments can be made on the STrac 700. The most important
adjustments are described under this chapter.

Remove the air filter housing and remove the nut which holds the air
filter. Take the air filter out and clean it carefully with compressed air
blowing from the inside to the outside of the filter. Always replace
damaged air filters. Replace air filters once a year or every 500 hours.
7.2 Check oil level: see 5.1.2
7.3 Replenish motor oil: Take precautions to prevent oil spills. Carefully
remove the oil drain plug from the bottom of the engine. Let all oil drain
into an oil pan. When all oil is out, re-insert the drain plug and carefully
fill the engine with the correct engine oil (see 2.0 Technical specifications)
For checking the oil level see 5.1.2.
