Vertical line viewfinder ensures perfect verticality of lifted weights
The vertical line viewfinder ensures perfect verticality of the lifted weights, prevents possible collisions with obstacles and people, and can easily lift heavy objects even when the line of sight is blocked. The horizontal load path allows the cargo to be moved to the prominent position more efficiently and accurately, even at blind spots, which greatly improves the comfort of operation.

Variable valve timing (VVT) solenoid or oil control valve controls the oil flow according to the engine speed and load. VVT solenoid is a vital part of the variable valve timing system.
The Oil Control Valve (OCV) is a a critical part used in every engine that is fitted with variable valve technology (VVT). A single control valve will regulate the supply of oil to a designated VVT hub, to advance or retard the timing by altering the camshaft angle position. Controlled by the ECU, the OCV receives electrical signals, instructing it to adjust the oil flow as required, in accordance to current driving conditions.
