Across its five sections the manual moves from routine upkeep to component-level repair. The scheduled maintenance portion defines what has to be checked daily, quarterly, annually and bi-annually, then walks through function tests that confirm the platform raises, lowers, steers, drives, brakes and levels as designed. From there the tables give the numbers a technician needs to work to – capacities, fluid types, fastener and hydraulic coupling torque values, floor loading pressure and machine weights. The schematics section supplies the hydraulic and electrical maps for the machine, including manifold port identification and the various engine and control-box configurations. The troubleshooting section is organised as numbered fault charts, each listing probable causes alongside the remedy, so a technician can work from symptom to failed wire, relay, coil, switch or valve. Finally, the procedures section gives step-by-step instructions with torque values and adjustment figures for the work that keeps these lifts in service.

What This Manual Covers in Depth

Because it is written for both models, the Skyjack SJ6826 RT and SJ6832 RT service manual separates the shared content from the model-specific detail. Where a specification or adjustment differs between the SJ6826 RT and the SJ6832 RT, the manual states the figure for each – for example the lowering orifice diameter and the working and elevated platform heights. Coverage extends to the Kubota diesel and Kubota dual fuel engine variants, to machines with and without the outrigger option, and to both rotary switch and toggle switch platform control boxes, with dedicated electrical schematics for each combination.

Safety material is included up front rather than buried: the minimum safe approach distance table for energized power lines, electrocution hazard warnings, jobsite inspection guidance and the operating precautions that apply before any maintenance or repair is attempted.

Who This Manual Suits

Owners and operators of an SJ6826 RT or SJ6832 RT who are responsible for the inspection schedule will find the checklists and the owner’s annual inspection record useful for keeping a documented maintenance history. Service technicians and workshops working on these scissor lifts get the fault charts, wiring and hydraulic diagrams, pressure setting procedures and torque tables needed to diagnose and repair rather than replace by guesswork. Fleet maintenance departments can standardise inspection and repair practice across both models using one document.

Why It Matters

These are mobile elevating work platforms that carry people at height, so incorrect adjustment or an unchecked fault is not a minor inconvenience. Working from the manufacturer’s stated pressures, torque values, limit switch settings and diagnostic sequences is what keeps the machine operating within the limits it was designed for. The troubleshooting charts in particular shorten diagnosis by pointing to the specific wire numbers, relays, diodes and coils involved in each fault rather than leaving a technician to trace the whole circuit.
