The TL49J can be fitted with a variety of power options. The battery powered machine has only one solenoid valve fitted (SOL 1). Both the engine and the mains powered version have a separate dump valve fitted (SOL 2).
In a situation where the ground controls function well but the operation of the boom from the platform controls does not work, then the valve responsible for making the booms lift/lower is the faulty valve. Page 3 - 12 TL49J Courtesy of Crane.Market...
Also look for contamination in the valve or valve cavity. To check that power is reaching the coil, hold a Figure 3-11: Diverter valve schematic. screw driver against the end of the coil. When the TL49J Page 3 - 13 Courtesy of Crane.Market...
RESTRICTORS All valve blocks have restrictors fitted at different locations. The current versions (2002) of the TL49J uses a hose adapter with a drilled hole. Other types which have been in use (and currently are on other machines) are a simple copper washer with a sized hole. The copper washer is squashed between the hose fitting and the adapter screwed into the valve block.
• Remove the bell housing to check that each coupling half is secured on the shaft. Then re- move the pump and check the internal gears. TL49J Page 3 - 15 Courtesy of Crane.Market...
The level gauge used for setting up the machine is located next to the outrigger control valve block. If the level is damaged or has been removed, do not use the machine until a new level has been fitted. Level Gauge Figure 3-19: Level gauge location. TL49J Page 3 - 17 Courtesy of Crane.Market...
Note If in doubt, replace or ask Snorkel or its local representative for advice. NUTS & BOLTS Replace any missing bolts immediately. The main pivot shafts and pivot pins are secured with one or two locking pegs.
When towing, insert the pin and lock in place with the “R” clip provided. During inspection, look for indication of the machine being moved without the pin. Signs of damage include dents in the top boom and crack lines below the vertical boom. Contact Snorkel or its local representative for repairs. R Clips Fixing Clips Figure 3-21: Level gauge location.
